2. Half fill the boiling tube at one end with Sodium Hydroxidde

3 Half fill the boiling tube at the other end with Hydrochloric

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

5. using pipettes you will add drops of the acid or alkiline to the test tubes to make colours of Red, orange, yellow, green, blue, violet.

3. add 3 drops of hydrochioric acid to the red litmus paper in test tube 2.

4. add 3 drops of sodium hydroxide to the blue litmus paper in test tube 3.

5.add 3 drops of sodium Hydroxide to the red litmus paper in test tube 4.

We did the expierment and it was pretty amazing. The hydrochioric acid turned the blue paper red and the hydroxide turned the red paper blue.
