 Kia Ora Readers, 

Today we are learning how to use/learn about pH.

Here is some steps.

1. Take a test tube rack with 1 boiling tube at each end of the rack and 4 test tubes.

2. Half Fill the boiling tube at the one end will Sodium hydroxide.

3. Half Fill the boiling tube at the other end with Hydrochloric acid.

4. Fill each test tube with 5 drops of Universal indicator.

5.  Using the pipettes you will add drops of the acid or alkaline to the test tube to make colours of RED, ORANGE, YELLOW, GREEN, BLUE, VIOLET.

6. DO NOT MIS UP THE PIPETTES.

Here is a photo of the results.
