will adding bananas help in my soap?

Question

im doing this investigatory project on how potassium affects the soap but i found out potassium content in bananas is low and that pure potassium would burn in water.. is there a way to extract potassium (or a compound of it) from another source that is not difficult to obtain?

Answer 1

You must buy potassium salts supplements at supermarkets or health stores. The best for your use is potassium chloride, but there may also be amino or carbohydrate salts.

Answer 2

Th form of potassium in soap is potassium hydroxide, commonly called caustic potash.
