Question

1. what is the reason why bubbling occurs when vinegar is mixed with baking soda?

o a gas is produced
o a precipitate forms
o a color change occurs

Explanation:

When vinegar (acetic acid, \(CH_3COOH\)) reacts with baking soda (sodium bicarbonate, \(NaHCO_3\)), a chemical reaction occurs. The reaction is \(CH_3COOH + NaHCO_3=CH_3COONa + H_2O+CO_2\uparrow\). The bubbling is due to the production of carbon dioxide (\(CO_2\)) gas. A color change (first option) is not the reason for bubbling in this reaction. Precipitate formation (second option) also does not happen here as the products \(CH_3COONa\) (sodium acetate) is soluble in water and \(CO_2\) is a gas.

Answer:

a gas is produced
