Question

Explain by writing a word equation.

Bubbles are seen on adding lemon juice to baking soda.

Solution

Bubbles are seen on adding lemon juice to baking soda because lemon juice is citric acid and baking soda is sodium bicarbonate. On adding lemon juice in baking soda, we add acid in base then neutralization reaction is taking place resulting in the formation of salt ,water and brisk effervesence of carbon-dioxide.This CO2 is released in the form of bubbles.

H3C6H5O7(aq) + 3 NaHCO3(aq)  → Na3C6H5O7(aq) + 3H2O(l) + 3CO2(g) citric acid + baking soda → salt + water + carbon dioxide

  Is there an error in this question or solution?
