Question

Why does an "acid spill kit" often contain baking soda?
Question options:

A) Baking soda is a weaker acid, which will raise the solution's pH.

B) Baking soda will absorb the acid so that it can be swept up.

C) Baking soda is a strong base that will react violently with the acid.

D) Baking soda is a weak base and will neutralize the acid.

Answer 1

Baking soda neutralizes the acid so D

Answer 2

Baking soda is a weak base and will neutralize the acid.

Explanation:

• The baking soda's chemical name is sodium hydrogen carbonate with a molecular formula of $NaHCO_3$.
• It is basic in nature and neutralizes the acid.
• It is a weak base, actually an alkaline salt of a strong base, and weak acid.
• The general reaction of baking soda with acid is given as:

       $NaHCO_3+HA\rightarrow NaA+H_2O+CO_2$

        (Where: HA is the general formula of an acid)

That is why the baking soda is present in the acid spill kits. So from this, we can conclude that the correct answer is option D.
