A) Measure the pH of different household chemicals
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.

Answer:
Chemical reactions occur slower at lower temperatures and faster at higher temperatures. When you put a glow stick in cold water, the chemical reaction slows down but will last for a longer period of time. When you put a glow stick in hot water, the reaction speeds up but will be over quicker.
