Solution

When a pinch of sodium hydrogen carbonate is added to acetic acid in a test tube, a brisk effervescence is observed due to colourless and odourless gas, which is $C O_{2}$ .
Chemical equation for the reaction :
$C H_{3} C O O H (a q) + N a H C O_{3} (s) \to C H 3 C O O N a (a q) + H_{2} O (l) + C O_{2} (g) ↑$
