Experiment 19-The Litmus Paper Test

                                                               Experiment 19

AIM: 

To determine the acidity or basicity of different substances using litmus paper.
.

APPARATUS AND MATERIAL REQUIRED: 

1. Litmus paper
2. Acids and bases (vinegar, lemon juice, baking soda, ammonia)
3. Water

LITMUS PAPER TEST IN ACID AND BASE

OBJECTIVES:

• To learn how to use litmus paper to test the acidity or basicity of a substance.
• To compare the acidity or basicity of different substances.

RESULTS:

Litmus paper turns red in acidic solutions and blue in basic solutions.

Vinegar and lemon juice are acidic, while baking soda and ammonia are basic.

Water is neutral, meaning that it does not have an acidic or basic pH.

CONCLUSION:

The litmus paper test is a simple and easy way to determine the acidity or basicity of a substance. This experiment showed that vinegar and lemon juice are acidic, while baking soda and ammonia are basic. Water is neutral.
