Question

list two observations which you make when you add a pinch of sodium hydrogen carbonate to acetic acid in a test tube . write chemical equation for the reaction that occurs​

Answer 1

NaHCO3 + CH3COOH =====> CH3COONa+ H20 + CO2.

Hydrogen gas is evolved which can be tested with matchstick. It burns with a pop sound.

Answer 2

NaHCO3+CH3COOH---: CO2+H2O+CH3COONa^+

2 observations are

1. a gas is realesed i.e. CO2 which turn lime water milkey

2.a salt is produced
