Used materials
- Powder Yellow
- Pieces of Page
- Water
- Forcep
- Bowl x3
- Liquid Soap (For Experiment)
- Lemon (For Experiment)
Process of making
At first I have taken some yellow powder in a bowl. Then I have mixed water on it.
Then I have soaked two pieces papers in yellow one bye one with forcep and made dry those papers. I soaked two pieces of paper beacause if one paper was spoiled, I might use another.
After completing make acid-base indicator by using yellow.
Experiment
I have taken some liquid soap in a bowl. We know that soap is on kind of base. I have soaked a yellow paper on the bowl.
Then yellow paper turned into pink.
Then I have taken lemon juice in a bowl. We know that lemon juice contains acid.
Then I have soaked the pink paper in the lemon juice.
Then it turned into yellow again.
Base make yellow acid-base indicator into pink and Acid make pink acid-base indicator into yellow.
This kind of acid-base indicator was discovered many years ago. I haven't made this first.
