Question

What is the chemical equation when vinegar and baking sodais passed through lime water?

Answer 1

Answer:

The reaction involved in this can be written as follows:

CH3COOH + NaHCO3 → CH3COONa + CO2 + H2O

CO2 + Ca(OH)2 → CaCO3 + H2O

These are the examples of chemical changes. In the first case, a new substance; carbon dioxide is formed. In the second case, a new substance; calcium carbonate is formed. The lime water turns milky because of formation of calcium carbonate.

These reactions are irreversible, as original substance cannot be retrieved from these by simple physical processes.
