Aim:
I want to find out what the colours of pH are.
Research:
Method:
Equipment:
- Acid-Hydrochloric Acid
- Base-Sodium Hydroxide
- Test Tube Rack with Test Tubes
- Universal Indicator
Instructions:
- Get all your equipment
- Put 10 drops of Universal Indicator into the test tube.
- Add different amount of acid and base into the test tube.
- Watch what happens when the colour evovles.
Results:
5.What are the pH colours?
R O Y G B I V/Red, Orange, Yellow, Green, Blue, Indigo, Violet.
4.How do you measure acid levels? You meausre acid levels on a strip of litmus paper.
3.What happens when you react an acid and a base? The reaction of an acid with a base is called a neutralization reaction. The products of this reaction are a salt and water, they like to fight each other and some pH colours can evolve when they both react.
