HCl obtention from bleach and acetic acid (vinegar).

I have always been curious to know if it is possible to obtain hydrochloric acid (HCl) from chlorine-based bleach and acetic acid (vinegar). I found a lot of answers saying that it was impossible and dangerous because you wouldn't obtain HCl; instead, you would get chlorine gas, which is a very dangerous fume that can cost your life. However, I found an answer saying that it was possible to synthesize it, but not directly from bleach. First, you have to mix equal quantities of bleach and acetic acid to obtain hypochlorous acid (HClO) and then you have to add a transition metal oxide (iron oxide, copper oxide, etc.) to get HCl and oxygen gas.  Filled with curiosity and keeping in mind that safety is the priority, I decided to try it out by mixing equal portions of bleach (NaOCl) and acetic acid (C2H4O2), obtaining an aqueous solution of hypochlorous acid (HClO) and sodium acetate (C2H3NaO2).  NaClO + C2H4O2—> HClO + C2H3NaO2 Then, I added copper oxide (rusty pennies) since I know that copper by itself reacts very slowly with HCl, so I could leave it there until the copper oxide had completely reacted with the HClO (leaving clean pennies).  Little but numerous bubbles started to come out which I thought to be the oxygen gas leaving the hypochlorous acid. I waited there until there were no more bubbles coming out which meant that the reaction had finished. To prove that it was HCl, I decided to add Aluminium foil and see if it reacted accordingly. However, nothing happened, so I tried the whole process of mixing bleach and vinegar again but when I got to the part of adding the metal oxide, I did not add copper oxide. Instead, I left it outside in the sun to react since I know that ultraviolet radiation causes fast disproportionation, forming HCl and oxygen gas.   HClO —> HCl + O2 After all the bubbles had finished coming out, I added Aluminium foil to prove that it was HCl. However, noting happened, and again, I obtained the same product as the last time.  I immediately stated to think of possible products that I could have obtained and the reasons why my reaction hadn't worked properly. It was then when I remembered that in the very first reaction (the one of the vinegar and the bleach) I had obtained a side product that I had completely forgotten about; sodium acetate (C2H3NaO2). And I suspect that this side product could have affected the whole process.  And that is my question; was it really the sodium acetate that one that affected the experiment or could have it been something else?

How to achieve a 'worn bleach" look on new clothes?

I often decorate clothes by partially bleaching ( see instructable Charles Mackintosh shirt. ) . I experimented with diluted bleach, bleach from pray cans, bleach from pointy nozzle bottles. I tried a lot and sometimes to my liking. I really would like to know how I can give self made clothes from plain material, often denim or cotton, a worn discoloration without distressing the fabric to the point its damaged. I looked on instructables, and the whole internet but found no answer. On the picture with the brown jacket ( bought, professionally bleached) you can see what I want to achieve. Especially the dotted seams with dark shadow and the discoloring of flap on the pocket and the hem. Other pictures show experiments that I did. I know how to make stains by knotting, binding, creasing. But that is not the answer I'm looking for.

Help! How do you do the acid-eaten clothing effect used by places like Lip Service Clothing? Answered

I accidentally tossed my favorite, and only, pair of solid white pants into the wash with colored clothes, and now there's a stubborn blue streak/splotch down one leg and on the hip. I've bleached it numerous times, but it hasn't budged, so I fear I may have to dye them- But before I take such extreme measures and have to kiss my white!pants good bye, I thought I might just... destroy the blue and create a nifty effect as well.

How to dye previously dyed material from IKEA?

I tried to do that in the washing machine with just copious amounts of bleach, and to my surprise no colour washed out!  It is a light green, so was thinking a crazy vibrant purple may be strong enough to change the colour, but am afraid it may go some weird gray-purple-brown colour instead.  Any pointers would be great thanks!  Yeah, I know, do a test strip... trying to save a step based on someones experience.

Can an artificial magnolia flower spray arrangement be dyed or bleached to lighten the petals?

My wife bought several artificial magnolia flower sprays a few years ago and prepared two very lovely arrangements, which have been decorating a wall in our living room.  Initially, the flower petals were an off-white color--but definitely white.  Now the petals have turned dark, and it appears they while likely darken even more if she is not able to do something to lighten this medium-tan tone that they now have.  I have looked at the material fairly closely and it looks like they are constructed from either a heavy paper or possibly a gauze, and then coated with a flexible substance by either dipping it or brushing it on.  The coating seems to be more in the nature of a stiffener for forming the petals, but apparently it has darkened with age.  Is anyone familiar with what I've described and have any suggestions?  (This is my wife's favorite arrangement and I would like to help her)  Thanks!

How can i use silver from x ray films to eletroplate a soldering iron tip?

That's it: i have a ton of old/useless x-ray films and a bare copper iron tip. I usually clean the x ray films with sodium chloride (at 2%, from bleach) to use the pvc sheets to make stencils. Once i left the resulting solution to air dry. It took something like a week for the 25cc of liquid to evaporate and left some crusty, green matter - which, i'm pretty sure,had silver in it. The questions are: what is that solution? Can it be used in eletroplating as-is or need to be refined? If yes, how? Put your brains to work, my friends! A silver-coated soldering iron tip is something of our common interest, i believe.

I have used bleach to make rust(with salt), how can I seperate the rust from the salt? Answered

I was looking for a way to make rust (ironoxide) and found that bleach coul be used as an oxidizer; however, I would not know when it was finished breaking down. With some research I found that NaClO + H2O2 -> O2 + NaCl + H2O. I think I can use this to either: use the NaClO and make the ironoxide, then add the H202 to break do the residual NaClO (extra H2O2 can be evaporated with the H2O), or used the reaction to speed up the ironoxide making with a bit of extra H2O2 to insure all the NaClO is used and the evaporate off the rest. (which would be better? would be my first question, but not the most pressing one) My question is how can I sepperate the Iron oxide from the NaCl (salt), since both are water soluble (sp)? A filter will seperate out larger pieces of ironoxide, but there will still be a fair amount that passes through the filter with the salt and I would like to minimize my loses as much as possible.

Swords and Souls

I was wondering how many people believe in swords having souls. I am a huge fan of Bleach, which refers to the Zanpakuto as being spirit beings, and I was reading a forum post somewhere that swords have personalities outside of their wielder's skill and the naming of a sword was based on the sword's personality. So, from this, I have chosen to believe that swords have souls and that one can communicate with their sword. So does anyone agree?

Yeast fermentation for composting solution?

I threw some hay off my lawn and some green weecds into a garbage can, some sugar and yeast and formented it to slug beer but the slugs did not like it. It then fermented further to vinegar, and a crust of green "Mold?" covered it. seems to have protected the vinegar from further fermentation. I tried a second bigger batch ( morning glory weeds) with less sugar but after a few days of good fermenting it went rotten and stinky. So there are probably thresholds for sugar content. Would the yeast be a way of adding fertilizer to organic gardens? Yeast can (I think) convert urea and nitrate to protein. Perhaps some green stuff has enough sugar to work without sugar addition. vine prunings? maybe. The first batch, i put bleach in to kill off microbes before I added water and yeast. Perhaps hydrated lime would work instead of bleach and also get the ph good for yeast fermentation. This might be a cheap way of liming your garden. (Here in victoria, hydrated type s lime is cheaper than limestone for garden addition. (But it contains more calcium!) The "yeast tea" or vinegar tea could be used on the garden and the weeds could then be transfered to normal compost or used as mulch. It might be an alternative way of using diseased materials of composting seedy weeds to kill the seeds. Brian
