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 your equipmeant
- Put ten drips of universal indicator into the test tube
- Add diffrent amounts of acid and base into the test tube
- Watch what happens to the colour
Result:
(Not my picture but similar to what we did)
Disscusion:
1. What is an acid?
An acid is a chemical. It is any substance that in water changes ur taste. For example sour, changes blue litmus paper to red, reacts with some metals to liberate hydrogen, reacts with bases to form salts, and promotes chemical reactions (acid lists).
2. " " a base
3.What happens when you react an acid and a base?
The reaction of an acid and a base is called a neurtalization reaction.
4. How do you measure acid levels?
You measure acid levels with pH. The range goes from 0 - 14 and 7 is the neutral. Anything below 7 is acid and anything above 7 is base.
5. What are the pH colours?
Red Orange Yellow Green Blue Indigo Violet
