In science we are going to be using litmus paper to see if something is an acid or a base. Here is what we learnt and did.
Materials
1. Red Litmus paper
2. Blue Litmus paper
3. Sodium Hydroxide
4. Hydrochloric acid
5. Pipette
6. 4 Test tubes
Steps
1. Rip the litmus paper in half and put half in each test tube.
2. Add 3 drops of hydrochloric acid to the blue litmus paper in test tube 1.
3. Add 3 drops of hydrochloric 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.
Conclusion and Findings
The blue litmus paper with hydrochloric acid went red.
The blue litmus paper with sodium hydroxide stayed the same.
The red litmus paper with hydrochloric acid stayed the same.
The red litmus paper with sodium hydroxide went blue.
In the end we didn't get told what the pH level was but we did get told if it was an acid or a base.
