Jul 12, 2021 at 12:58 | comment | added | alephzero | Potassium bicarbonate is used in agriculture as a fungicide, and as a soil conditioner to control acidity. It is also used in dry powder fire extinguishers, and as an alternative to sodium bicarbonate (baking soda) in cooking by people on a low-sodium diet. Depending how pure you need it, you should be able to find a source for it somewhere. | |
Jul 12, 2021 at 7:33 | comment | added | Poutnik | @Jaredbrandt K2CO3 is often available as well.// Just for curiosity - it is largely used in Dutch processing of cocoa ( cocoa gets from light brown to dark brown by the process ) to produce chocolate from inferior cocoa beans, enhancing cocoa flavour and removing acidity. | |
