Question

In soda-acid fire extinguishers.

Hint:

Baking soda is a versatile compound: It acts as an anti-acid, a leavening agent in baking, and helps extinguish fires by producing carbon dioxide when it reacts with acids.

Answer 1

In soda-acid fire extinguishers, baking soda reacts with an acid (like sulfuric acid) to release carbon dioxide gas, which helps extinguish the fire by displacing oxygen. The chemical equation for this reaction is: \[ NaHCO_3 (aq) + H_2SO_4 (aq) \rightarrow NaHSO_4 (aq) + CO_2 (g) + H_2O (l) \] Thus, the chemical property used here is the production of COsubscript{2} when it reacts with acids.
