Cason Villarreal · Answer 1

A. Liquid A became acidic first.

Explanation:

Here, we have 2 liquids, liquid A and liquid B.

Liquid A is just distilled water.

Liquid B is distilled water with crushed antacid tablet (base) added to it.

If we add vinegar that is an acid to both the liquids.

Liquid A becomes acidic since it has only distilled water.

Liquid B becomes neutral as it has antacid tablets (base) dissolved in distilled water, and so acid reacts with base and gets neutralized.

So A is the answer.
