When sodium hydrogen carbonate reacts with ethanoic acid, it forms sodium ethanoate salt, water and carbon dioxide.

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

So, salt X is Sodium ethanoate = $CH_3COONa$

Activity

1. Take sodium hydrogen carbonate in a test tube and add ethanoic acid

2. Carbon dioxide is evolved with brisk effervescence.

3. Pass the gas into lime water and if it turns white (milky), it means carbon dioxide gas is present. This is the conformation test for carbon dioxide.

$Ca(OH)_2 (aq) + CO_2 (g) \rightarrow CaCO_3 (s) + H_2O (l)$
