how can i make sodium hypochlorite bleach from rudimentary material.

Please help me to make sodium hypochlorite bleach from rudimentary material for sterilisation purposes ( i was told by a US trained man that it was so) someone told me to check you out on the net.(that u knew all sorts of wonderful hands-on chemistry) and for mouth wash. it is for a rural health post in northern ghana. we buy the stuff from accra and transporting it across the country to the north is making the cost difficult for the rural folks here to afford. but they need it as cheap as possible for hygiene purposes.

chemistry assistance please!?

If not, tell me a simple way. (if there is one...)

Caustic Soda vs Soda Ash, using to clean a bast (stem) fiber. Do they have the same affect on the strength of the fiber? Answered

I'm working on a project to clean (dissolve) bark off of some fiber that adheres to the inside of the bark. I've used caustic soda (sodium hydroxide) successfully but it weakens the fiber. Soda ash (sodium carbonate) also works and seems to have less affect on strength but I'm wondering, chemically, if there's any real difference. I don't have access to any gear to accurately measure the real tensile strength. Thanks for your help. Shanti Mama Kathmandu Nepal

Does synthesizing Sodium Chlorate NaCl03 produce any harmful fumes if i electrolyize the solution while it is hot? I saw on wiki if you heat the solution while electroyzing the solution the reaction is NaCl + 3H2O = NaClO3 + 3H2 but if it isnt hot the reaction is 2NaCl + H2O = NaClO + NaCl + H2O , NaClO (Sodium hypochlorite) is what is used in household bleach.

How can I purify mineral oil?

My early experiments with oil-cooling my PC lead to some chemical *discoveries* The first was mineral oil will dissolve latex rubber.  I was using surgical tubing to pump the oil to the radiator and after a day the tubes had softened and swollen so much they wouldn't stay attached to the pump.  That and the oil turned an ugly yellow. (* the second was warm oil reacts with PVC, and causes the insulation on usb cables to become brittle) I'm working on the next gen of the project and I'd like to clean up the oil, but I can't quite google my way to a solution. I have filtered the oil (removed all the bugs) though a coffee filter, and a couple of paint filters, I don't have any reason to believe the rubber is suspended and filterable, but I could be wrong. Any chemists out there know what I can do?

Dissolve Aluminum - Golden Book Chemistry

In the Golden Book of Chemistry, page 64, there're instructions for dissolving aluminum. The book states that HYDROGEN is released when aluminum strips are dissolved in hydrochloric acid and ALUMINUM CHLORIDE is formed. That's about all we get from the book concerning that particular experiment. Just wondering if this is correct, how to test it, what it should look like and what may we [the kids and myself] may do with it if it's actually aluminum chloride. It's a good book, but quite a bit of theory's lacking. Thanks all.

Chemistry set DIY gas mantle?

I'm looking for some help tracking down a chemistry experiment I tried as a child and would like to replicate.  As I recall it involved dissolving a solid (perhaps limestone) in a liquid (possibly vinegar), soaking some cloth in the resulting solution and burning it over a flame when it dried.  The idea was that the cloth would burn away and leave a mesh of whatever it was, probably lime, that acted as a mantle.  I tried it as a child and had limited success (I was too impatient to get some appropriate cloth or wait for it to dry properly) and would like to try it now that I'm older and wiser older. If it does have to be limestone, any ideas how I can hold of small quantities without having to go to the local chalk quarry?
