# Potassium hydroxide neutralization with acetic acid

I put 9% acetic acid to 60% potassium hydroxide solution to neutralize it and was hoping to see some fizzing, but didn't see any indication of them reacting. Why is that?

• People often neutralise acetic acid with a weak base such as sodium hydrogen carbonate, which liberates carbon dioxide gas as the reaction proceeds in addition to the other neutralisation products. – NotEvans. May 20 '17 at 14:44
• The reaction for this would be: $$\ce{CH3COOH + KOH -> CH3COO^{-}K+ + H2O}$$ There are no gaseous products, so you can't really expect any fizzing. – Pritt Balagopal May 20 '17 at 14:52

$$\ce{CH3COOH + KOH -> CH3COO^−K+ + H2O}$$
$$\ce{CH3COOH + NaHCO3 -> CH3COO^−Na+ + H2O + CO2 ^}$$
With this we are forming $\ce{CO2}$ gas, which will cause the solution to effervesce. Note that this is likely to be stinky and messy: a good experiment to perform outdoors.
