Which substance neutralizes small acid spills?

Neutralizing a small acid spill relies on using a substance that can react with the hydrogen ions to form water and a salt, reducing acidity quickly. Baking soda, sodium bicarbonate, acts as a mild base. When it meets acid, it reacts to form carbon dioxide and water plus a sodium salt, effectively neutralizing the spill. A simple way to see it is NaHCO3 + H+ -> Na+ + CO2 + H2O. This reaction not only lowers acidity but also gives a visible fizz indicating the neutralization is happening, which helps guide cleanup. Water only dilutes the acid and can spread it, while vinegar is itself acidic and would not neutralize; sand absorbs liquid but doesn’t neutralize the acid. So baking soda is the best choice for small acid spills.
