What is observed when a pinch of sodium hydrogen carbonate is added to 2 mL of acetic acid taken in a test tube? Write chemical equation for the reaction involved in this case.

Academic Chemistry NCERT Class 10

CO₂ gas is evolved with brisk effervescence when sodium hydrogen carbonate is added to acetic acid.

The equation is given below:

$NaHCO_3 + CH_3COOH \rightarrow CH_3COONa + H_2O + CO_2$
