chuckie walters Posted November 23, 2009 Share Posted November 23, 2009 Is it possible to make potassium hydoxide by mixing potassium chloride and distilled water? I read somewhere that it was but dont remember where. Quote Link to comment Share on other sites More sharing options...
topofmurrayhill Posted November 23, 2009 Share Posted November 23, 2009 I'm not a chemist, but I believe KOH is made from such a solution through electrolysis. It requires an electric current and there are other significant considerations to accomplishing it. You can't do it effectively and safely on your own unless you're a chemical engineer. Plus you'd have to figure out what to do with the poisonous chlorine gas. Quote Link to comment Share on other sites More sharing options...
JacquiO Posted November 23, 2009 Share Posted November 23, 2009 I'm no chemist either but that doesn't sound right. IMHO just buy the KOH online. The Chemistry Store carries it and so does AAA Chemical I think. I know that soap in the ol' days was made with potash. You can find plenty of info online on how to make potash by running rain water through wood ash but I wouldn't know how to calculate the potash to fat ratios to make soap.

chuckie walters Posted November 23, 2009 Author Share Posted November 23, 2009 The reason i ask is because i saw a reciepe for crockpot liquid soap and it calls for potassium choloride.The lady says that when you add the pottasium chloride to the distilled water in the crock pot it forms pottasium hydroxide while the soap is cooking.Ever heard of this? Thanks:) Quote Link to comment Share on other sites More sharing options...
Kitn Posted November 23, 2009 Share Posted November 23, 2009 I've never heard of it . If it were so, I think more of us would make soap that way or at the least we know about it . I could be totally wrong here too I don't know . Quote Link to comment Share on other sites More sharing options...

Thanks:)There's something wrong, there. Like Top said, you'd have chlorine gas as a by product. If a lot of people were trying to do this, there'd be a lot fewer people making soap. The chlorine gas is deadly even in small amounts. It was used as a weapon in WWI. It turns the moisture in your lungs into hydrochloric acid.This link verifies what Top was saying about electrolysis.So if you short circuit your crock pot, it might work. And if you have a gas mask, you might actually survive it. Quote Link to comment Share on other sites More sharing options...

JacquiO Posted December 5, 2009 Share Posted December 5, 2009 I looked at that recipe and I think she got her chemical names mixed up. If you want to make a liquid soap you need KOH (i.e. potassium hydroxide). Buy some KOH from an online supplier and find a good liquid soap recipe and run it through the soap calc. I don't think you could get lye from potassium chloride and distilled water any more than you could get sodium hydroxide from table salt (i.e. sodium chloride) and water. At least not in your crockpot lol! Both have to go through a process of electrolysis. As for producing chlorine gas I can't find any reference to boiling potassium chloride in water to create chlorine gas. Chlorine gas can be produce by mixing bleach with ammonia. Not something I recommend unless you want to die a gruesome death. Quote Link to comment Share on other sites More sharing options...
LuminousBoutique Posted December 14, 2009 Share Posted December 14, 2009 Yikes. that lady really should correct or remove that recipe, it could cause serious harm to someone. Quote Link to comment Share on other sites More sharing options...
