Question

baking basics quiz
baking soda reacts chemically with acidic liquids to produce carbon dioxide gas, which expands when heated.
true
false

Explanation:

Baking soda (sodium bicarbonate, \(NaHCO_3\)) reacts with acidic substances (e.g., vinegar which contains acetic acid \(CH_3COOH\)). The chemical reaction is \(NaHCO_3+CH_3COOH = CH_3COONa + H_2O+CO_2\uparrow\). The carbon - dioxide gas produced gets trapped in the batter. When heated, gases expand (due to the increase in kinetic energy of gas molecules according to the ideal gas law \(PV = nRT\), where \(V\) is volume, \(T\) is temperature, and as \(T\) increases \(V\) increases for a fixed \(P\) and \(n\)).

Answer:

True
