Answer

Answer:

A. Acids measure below 7.

Explanation:

Step1: Recall pH scale basics

The pH scale ranges from 0 - 14.

Step2: Define acidic substances

Substances with a pH below 7 are acids.

Step3: Define basic substances

Substances with a pH above 7 are bases.

Step4: Analyze options

Option A is correct as acids have pH < 7. Option B is wrong as bases have pH > 7. Option C is wrong as acids have pH < 7 and bases have pH > 7. Option D is wrong as neither acids nor bases have a pH of 7 (pH = 7 is neutral).
