Question

Effervescence formed well batter of cake is heated. Which substance is present in batter. Name the gas evolved and write chemical equation.

Answer 1

it will be in batter

Answer 2

Explanation:

Effervescence formed when batter of cake is heated is due to the presence of a substance called sodium bicarbonate. It has the molecular formula $NaHCO_{3}$.

When sodium bicarbonate is heated, it decomposes to give sodium carbonate along with the release of carbon dioxide gas and water.

The chemical equation for the reaction is as follows.

      $NaHCO_{3} \overset{heat}{\rightarrow} Na_{2}CO_{3} + CO_{2} + H_{2}O$
