Potassium acetate (CH3COOK) is a chemical compound.
It can be prepared by reacting a potassium containing base such as potassium hydroxide or potassium carbonate with acetic acid: 2CH3COOH + K2CO3 → 2CH3COOK + CO2 + H2O This sort of reaction is known as a acid-base neutralization reaction. Potassium acetate is the salt that forms along with water as acetic acid and potassium hydroxide are neutrilized together.
Conditions/substances to avoid are: moisture, heat, flames, ignition sources and strong oxidizing agents.
