Question

Salt solution that changes into blue litmus to red is called
1.acidic
2.basic
3.salts
4.sugar​

Answer 1

Answer:

Neutral salt → No change in the colour of litmus

Acidic salt → Turns blue litmus to red

Basic salt → Turns red litmus to blue

When a red litmus paper is immersed in a base or alkaline solution, the red litmus paper turns blue indicating the given solution as alkaline/base. Bases are ions that break up to form OH

−

(hydroxide) ions in water. The greater the concentration of OH

−

ions, the stronger is the base.

For example, Sodium Hydroxide, Ammonia Solution.

Blue litmus paper is used to test an acid. When a blue litmus paper immersed in an acid, the litmus paper turns red from blue indicating acid. Acids are ions that break to H

+

in water. The greater the number of H

+

ions, the stronger is the acid.

For example, hydrochloric acid, Sulfuric Acid, Carbonic acid.

No change in the colour of litmus means neutral or pH =7.
