What is the chemistry of this household cleaning recipe?
Baking soda is sodium bicarbonate, and vinegar is dilute acetic acid. Common salt (table salt) is sodium chloride. Sodium bicarbonate will react with acetic acid to form sodium acetate (in solution), carbon dioxide gas, and water. Sodium chloride will not participate in the reaction. The reaction equation would be:

$$
\ce{NaHCO3(s) + HCH3COO(aq) -&gt; NaCH3COO(aq) + CO2(g) + H2O(l)}
$$
