Question

A substance has a pH of 8.0. How would it be classified?
A. Weak base
B. strong acid

Answer 1

A substance with a pH of 8.0 would be classified as a **weak base**. In general, a pH of 7 is neutral, values below 7 indicate acidity (with lower values representing stronger acids), and values above 7 indicate basicity (with higher values representing stronger bases). Since a pH of 8.0 is above 7, it suggests a basic nature, but it is not strongly basic, thus classifying it as a weak base.
