What Colour Does Litmus Paper Turn When Dipped In Acid?

When litmus paper is dipped in an acidic solution, it turns red. This is due to the reaction between the acid and the litmus paper, which causes a change in the pH level of the paper. Litmus paper is a commonly used indicator in chemistry to determine whether a substance is acidic or basic.

The red color change in litmus paper indicates that the substance being tested is acidic, with a pH level below 7. Acids are substances that release hydrogen ions when dissolved in water, which is what causes the change in color of the litmus paper. This reaction is the basis for using litmus paper as an indicator for acids.

On the other hand, when litmus paper is dipped in a basic or alkaline solution, it turns blue. This color change is the opposite of what happens when the paper is dipped in an acidic solution, indicating that the substance is basic with a pH level above 7.

Litmus paper is a simple and effective way to test the acidity or alkalinity of a substance quickly and easily. It is widely used in laboratory settings and is a staple in chemistry classrooms for demonstrating acid-base reactions.

For more information on litmus paper and its uses in chemistry, you can visit Chemguide for detailed explanations and examples of acid-base indicators. Understanding how litmus paper works can help you better understand the principles of pH and chemical reactions in the laboratory.

In conclusion, litmus paper turns red when dipped in an acidic solution, providing a clear visual indication of the presence of an acid. This simple yet effective tool is a valuable asset in chemistry experiments and is a great way to learn about acid-base reactions.
