A litmus test is used to determine if a substance is an acid or a base.  If the test strip turns blue, then the substance is a base.  If the test strip turns red, then the substance is an acid. 

Acid makes concrete or metal corrode.

pH level is the measure of acidity or alkalinity of a solution.

A negative catalyst can slow down a chemical reaction.
