Potassium acetate
Potassium acetate (KCH3COO) is the potassium salt of acetic acid.
It can be prepared by treating a potassium-containing base such as potassium hydroxide or potassium carbonate with acetic acid:
This sort of reaction is known as an acid-base neutralization reaction. Sesquihydrate in water solution (CH3COOK·1½H2O) begins to form semihydrate at 41.3 °C. Potassium acetate is the salt that forms along with water as acetic acid and potassium hydroxide are neutralized together.
