Mo4-L3b: What is the pH of a Solution?
The pH of a solution can be measured by dipping a SUMMARY
pH testing strip into the solution.
What is the pH of a Solution?
Hydronium ion concentration changes
inversely with pH.
This means that as hydronium ion
concentration increases, the pH decreases.

A more accurate way to measure pH is to use a pH H
meter.
