Answer

Explanation:

Step1: Use pH - paper

Use a piece of pH - paper to test the liquid. Dip the pH - paper into the liquid carefully.

Step2: Interpret results

If the pH - paper shows a pH around 7, the liquid is water as water is neutral. If the pH - paper shows a low pH (below 7), the liquid is battery acid as battery acid is acidic.

Answer:

Use pH - paper. If pH is around 7, it is water; if pH is below 7, it is battery acid.
