Kid Friendly Kitchen Chemistry

Today we are going to become chemists and observe chemical reactions that vary according to a material's properties. Our chemical reaction tests are going to show us what materials are acids and what are bases.

Knowing about the basic properties of a material can help scientists develop new medicines for disease, make formulas like shampoo and soap, and also help us learn about ways we can better our natural environment.


Materials:

So, what is an acid? What is a base? An acid is a compound that contains hydrogen. Some acids taste very sharp. Look at the material list for the things that you guess might be an acid. Can you guess before you test? A base is the opposite of an acid. Bases react with acids to make salts.

Scientists use the pH scale to measure how acidic or basic a liquid is. They have tools that measure pH in numbers. Anything between 0 and 6 is an acid. Anything between 8 and 14 is a base. What number did I forget? 7! Seven means a liquid is neutral (neither acidic or basic)

Another way to test whether something is an acid or a base is using red cabbage. Shall we try?
