## Step 4: Extra Fun

I was thinking and remembered that the reason why the solution glows is because the Potassium ferricyanide excites the electrons or something and makes them glow, and so i had the idea to run an electric current through it and it started to glow a bit, THEN i had the idea to tazer it, looked alot better, you can kinda see in the picture the blue glowing wire, it did look alot better in real life. but just have fun with it, it also looks really cool in the toilet, or on your skin.

Ask if you have any questions

Enjoy!
Which part is confusing?
<p>everything and hoe science you are I don't know what anything you're saying means. All I know is the H2O part and the rest is so confusing!!</p>
<p>Ok...umm...let's see...</p><p>Sodium bicarbonate (baking soda) decomposes into sodium carbonate at temperatures above 50 degrees Celsius (122 degrees Fahrenheit) yielding carbon dioxide and water vapor. At 200 degrees Celsius (392 degrees Fahrenheit) this decomposition is rapid and somewhat violent as the evolved gases tend to cause sodium carbonate to bubble and become airborne.</p><p>Sodium carbonate (washing soda) decomposes into sodium oxide, carbon dioxide and water vapor at 851 degrees Celsius (1563.8 degrees Fahrenheit; see incandescence chart for visual example of temperature). </p><p>Sodium oxide is very slowly added to cold, distilled water to create sodium hydroxide solution. And that's pretty much the long and short of it. :D </p>
Doesn't sodium bicarbonate decompose into sodium carbonate, water, and CO2? Obviously, the CO2 and water will simply be given off as gasses.<br>I have 2 questions then:<br>Does the average kitchen stove even reach 500+ F, and how do you turn NaCO3 into NaOH?
<p>Sorry to have left you hanging for ...well pretty much forever. On a gas range (with some type of enclosure) yes, you can convert baking soda directly to sodium oxide. On an electric range (again with the enclosure) it will depend entirely on the capacity of the heating element. See above for additional info.</p>
Yessir, the average stove reaches way higher than 500 degrees! <br>You can drop zinc match box cars in a pot and melt them on the stove. <br>Or pennies. You can melt a whole pot of pennies (called pot metal). That is hot hot hot hot. You can feel the heat coming at you when you are near it.
<p>so does all of this work like what you commented bec i am doing it for my science fair project :D</p>
<p>Additionally, if [and this is a big &quot;if&quot; since I don't know what your current tech capacities are] you have a means of safely heating the sodium carbonate produced by the above process to 851C/1563.8F it will further decompose into sodium oxide and carbon dioxide. Once cool, sodium oxide may then be slowly hydrated with distilled water to yield sodium hydroxide. This is a fairly dangerous method of producing sodium hydroxide without any intermediary steps so goggles, respirator and gloves are not optional. And you probably would be doing right to have on some kind of coverall and a jug of straight vinegar at the ready.</p>
My apologies, echaa was correct and I definitely got carried away and got careless. That's what I get for trying to be funny...<br><br>Anyway, there are more steps involving reaction of sodium carbonate (actual product of the above mentioned thermal decomposition process) with calcium oxide a.k.a &quot;quick-lime&quot; (product of a similar thermal decomposition process that starts with chalk) in liquid solution whereby calcium carbonate precipitates out from the solution leaving sodium hydroxide. As cyclohexane mentioned, it will be of greater expedience to check a local hardware (certain dry crystalline and liquid drain cleaners), the dyes section of a crafts store (specifically marked sodium hydroxide) or a soap-makers' supply company. <br><br>Also, a lot of companies print &quot;It is a violation of federal law to use this product in a manner inconsistent with its labeling.&quot; on their products...which is troublesome at the very least. Check the label before you buy: if that warning is on it, you might have a problem if anyone starts asking questions about where you sourced your materials. In other words, try to find a source whose label simply states what's in the container, concentration percentage, the manufacturer and nothing else. Don't think you're going to need it, but good luck anyway. :D
There's absolutely no need to &quot;make&quot; your own sodium hydroxide....do a quick google search and you will find many resources for the chemical. Try this, i found it at Ace Hardware..... http://www.acehardware.com/product/index.jsp?productId=2845800&amp;cp=2845052
As a general reply for everyone's consumption and as a corrective measure to cover some things I left out of the original proceedural comment: <br> <br>1. So everyone knows what they're going for temperature-wise, sodium bicarbonate decomposes into sodium hydroxide at 270C/518F. <br> <br>2. Addition of water to dry-state sodium hydroxide sets up an endothermic reaction. Do this very, very slowly with cold, distilled water to avoid all possibility of flash-boiling.
Thanks so much but I do have one question. Can you use the dry NaOH just like the stuff you use to be able to buy? I have been making biodiesel for years and the meth heads have made my life more difficult.
I'm a little fuzzy on bio-diesel process but if your unit calls for dry-state NaOH, then absolutely you can. Just be certain that the gas evolution step is 100% complete and you'll be good to go. If it wants for a solution of a specific concentration, that's a little bit of a different animal but still completely do-able.
Isn't sodium hydroxide the crystals in drano? Or maybe Canadian drano is different?
According to the label, there is sodium hydroxide in Crystal Drano. Whether or not that's what gives it that nice sparkle I can't say; according to Wikipedia the crystals are just common salt, but I only half-trust Wikipedia. <br> <br>Anyway, given the other components of Crystal Drano, it probably wouldn't be suitable in this instance unless you could work out a process to remove the sodium nitrate, aluminium shavings and table salt...which actually sounds like a fun project in and of itself. Thanks for the idea!!!
Maybe a little bit more time at school.....
<p>lol right</p>
I thought I should point out a small typo, which caused at least two errors in your instructions that could cause further confusion&hellip; &nbsp;<br> <br> 1) &quot;Luminal&quot; is the trade name for phenobarbital, which is also the chemical formula that you list. Luminol ( C8 H7 N3 O2 ) is the chemiluminescent stuff that people want to make glowsticks.<br> <br> 2) C12 H12 N2 O3 is phenobarbital, which is a sedative and not chemiluminescent&hellip; It's a schedule-IV drug, which might be why searching for places to buy 'Luminal&quot; won't be fruitful (and I wouldn't necessarily trust that what you got in the mail was Luminal anyway).&nbsp;<br> <br> <br>
<p>good catch even tho I have absolutely no idea what you're talking about????????</p>
<p>What is the concentration of NaOH?</p>
<p>http://usuncut.com/news/sanders-supporters-death-glow-sticks/ These sticks are deadly and will kill you.</p>
<p>These aren't those glowsticks, but people should be careful just in case. </p>
<p>what percentage of hydrogen peroxide is used? 3% or 30%?</p>
<p>is it toxic? would it damage skin?</p>
<p>Sodium hydroxide IS corrosive, so it is unsafe for direct contact with skin or ingestion. It could cause a range from minor irritation to sever chemical burns, so stay safe. :)</p>
Where can I get the little tubes? I need to make sure it closes securely so that 5 year olds won't eat them. Help!
<p>awesome suace</p>
Can you make different colors other than blue?
potassium ferricyanide is K3[Fe(CN)6] .
when I was in the National Guard we cut a Chem Lite open and poured the liquid on an ---hole who was sleeping, then had him called to the commander's tent. Good laugh, but helped me know you can safely pour the fluid on children's Halloween costumes so they are easier to see from cars driving by.
Just because you could pour it on someone and not have instant pain and suffering doesn't mean its safe at all. I would not pour it on a kids costume you don't know how it might reacts to the materials the costume is made from. I'd worry most about some sort of fumes.
Usually the chem lite (glow sticks) say nontoxic on the packaging.
That sounds a lot like the actuall Bohr-Model of an atom. And yeah it works here ieven when it's not completly right.
It glows because when you excite it(give it energy) the eletrons jump to a new energy level, when they jump back to their normal energy level, they release that extra energy in form of light.
how long it will glowing ?
My question is, what do you recommend putting the mixture in to make it portable, yet safe? I can't very well give my child an open test tube to walk around with :P
I once purchased, I think @ Hobby Lobby, some plastic test tubes with screw on lids that would be perfect for this. They are actually unexpanded pop bottles. They are made of polycarbonate which is extremely tough, at room temperature you probably couldn't break one with a hammer. As a plus, the lids seal really well. They have to for soda pop. Look for them where kid's scientific stuff is sold. There, your crisis is solved. <br>By the way, my hat's off to the author. This is fascinating stuff.
Or just give your child a test tube full of glowing green liquid and see what happens. ;-P
Oops, my fault. In the &quot;make your own sodium hydroxide&quot; comment, roasting of sodium bicarbonate <strong>DOES NOT CREATE SODIUM CARBONATE</strong>.<br> <br> Rather, it&nbsp;converts NaHCO3 to NaOH (dry-state sodium hydroxide) by<br> driving off&nbsp;carbon dioxide.<br> <br> I'm getting old...things are starting to slip away.&nbsp;&nbsp;&nbsp; \: (
Will higher concentrations of hydrogen peroxide help or hinder the end result?
help.
I would be doing all the intense mixing BEFORE adding the H202. Being as unstable as it is, you could well find that the free O- has escaped...
Even if you stir it, it takes years for the O2 in H202 to escape. It is not very unstable, until a catalyst is added.
I like blue but, can you get other colors?
Use different chemicals than luminal
Omg. Its like a cooking show, but it glows and would probably would kill you if you ate it. All measured out, and &quot;But I prepared one earlier&quot; is all in here. <br><br>Good ible. Might have to do this, looks cool.
