Explanation:

To demonstrate a chemical property using an experiment, measuring the pH of different household chemicals will be the best way. The pH is the degree of hydrogen or hydroxyl ion concentration in a solution.

Chemical properties tell us about what a substance can do.

It shows if a substance will react with other substances or not.

Examples are flammability, rusting of iron, precipitation, decomposition of water by electric current e.t.c.

Measuring the pH is a chemical property determination procedure.

The pH points to the degree of acidity or alkalinity of a solution.
