Question

Answer

Red

Answer

Acid turns blue litmus red.

Explanation:
Litmus is a dye obtained from lichens that is commonly used as an indicator of pH. It is available in two forms - blue litmus and red litmus. Blue litmus is used to test for acids and turns red when it comes in contact with an acidic solution.

Acids are substances that donate hydrogen ions (H+) in aqueous solutions. When an acid is added to blue litmus, it reacts with the litmus to form hydronium ions (H3O+) which cause the litmus to turn red. This is because the hydronium ions react with the blue litmus to form a complex that is red in color.

The reaction can be represented as follows:
H+ (aq) + Blue Litmus → Red Litmus

Therefore, if a blue litmus turns red when it comes in contact with a solution, it indicates the presence of an acid in the solution.

Answer

Acid turns blue litmus red.

Litmus paper is used to test whether a given solution is acidic or basic. Litmus paper is made by soaking paper in a solution of litmus dye. When exposed to an acid or base, the paper changes color.

Acids have a pH less than 7 and can be identified using litmus paper. When an acid is applied to blue litmus paper, it turns red. This is because the acid reacts with the litmus dye, causing a chemical change that produces a red color.

Some common examples of acids that turn blue litmus paper red include:

- Hydrochloric acid (HCl)
- Sulfuric acid (H2SO4)
- Nitric acid (HNO3)
- Acetic acid (CH3COOH)

In summary, when an acid is applied to blue litmus paper, it turns red due to a chemical reaction between the acid and the litmus dye. This makes blue litmus paper a useful tool for identifying acids in a laboratory or other setting.

Answer

Acid turns blue litmus red.
Litmus paper is an indicator paper that is used to determine the pH of a substance. The paper is available in two colors - red and blue. The color of litmus paper changes when it comes in contact with an acidic or basic solution.

Explanation:
When blue litmus paper is dipped into an acidic solution, it turns red. This happens due to the presence of hydrogen ions (H+) in the acidic solution. Hydrogen ions react with the blue litmus paper, causing a change in the chemical structure of the paper, which results in a change in color from blue to red.

Acids are substances that produce hydrogen ions (H+) when dissolved in water. The more the concentration of hydrogen ions, the stronger the acid. Acids have a pH value less than 7. Examples of common acids include hydrochloric acid, sulfuric acid, and acetic acid.

Litmus paper is widely used in laboratories to determine the acidity or basicity of a solution. It is a simple and inexpensive way to determine the pH of a substance.

In conclusion, acid turns blue litmus paper red due to the presence of hydrogen ions in the acidic solution.

Answer

Option d red

Answer

D is the correct answer

Answer

Option D
acids turn blue litmus to red. Litmus turns blue when it comes into contact with acids. When blue litmus paper is placed in an acidic solution, it becomes red. However, when placed in a basic or neutral substance, it will remain blue.
