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 get the acid to neutralize the base without making the mixture of the acid and base become to acidic./
Include a photo of the final green solution.
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.
Put a photo of your rainbow in a test tube here:
