Why do you need to test solutions with Blue litmus paper and red litmus paper?
So you can tell if the solution is an acid or a base
Why is it important to use blue and red litmus paper to determine pH?
Because if you only use red litmus paper and the solution you tested kept the paper red, you would think that the solution would also make the blue litmus paper turn red too. But what if the solution was neutral? Then the blue litmus paper would stayblue instead of turn red. Thats why you need to use both blue and red litmus paper.
How do you use litmus paper?
A litmus paper is used to test the alkalinity or acidity of any substance. In the presence of an acid, a blue litmus paper will turn red and a red litmus paper turns blue to indicate the presence of alkaline.
Why does the litmus paper need to be damp?
Litmus paper needs to be damp because it relies on a chemical reaction between the paper and the substance being tested.

This ensures a more accurate and reliable measurement of the substance's pH level.
Why did you need to test with both red and blue litmus paper?
