Potassium Hydroxide

[janzo]

I sent an email to a chemical company asking if they have the above product. They have come back to me asking if I want the commercial or laboratory grade, I am ashamed to admit I do not know and not sure where to find those kind of details. Can anyone help please???

Commercial grade (90% purity) is what most of us use. If you are in the US, Essential Depot has it and free shipping on smaller orders.

Thank you for your reply, I am in Zambia, Africa and it seems it is difficult to find. One place quoted me $20 for 500g !!!!

Ah bummer! Well not that you are in Africa, that it's hard for you to find.

Not sure of your scale, but if I wanted Potassium Hydroxide and none were available, I might consider the wood ash approach. With a hydrometer it should be possible to get pretty consistent results.

Some chemicals are restricted because of political rather than actual need.
