Chapter 8 : Acid and Alkali
What will you learn in this chapter
We can test if something is acidic, alkaline, or neutral by using litmus paper.
If the paper changes color to red, it is acidic.
If it changes to blue or green, it is alkaline.
We can also use our taste and touch to make generalizations about substances.
For example, lemon juice tastes sour, so it is acidic.
Soap feels slippery, so it is alkaline.
Let's have fun investigating and testing different substances to learn more about acids and alkalis!
