Green and Rainbow challenges

A: Green challenge:

Take a test tube and fill with "two fingers" of the base. Now see the teacher for three drops of universal indicator. Now add the acid

Observations:

1. When we added the universal indicator to the base the colour changed to Blue .

2. When the solution was neutralized the colour changed to Green .

The most difficult thing about this challenge was trying to balance then base and acid

B: Rainbow challenge:

Take a test tube, the base and the acid and universal indicator and create a the best rainbow in a test tube you can manage.
