Question

Nitric acid turns red litmus blue.

• A. True
• B. False

Answer 1

The correct option is B False

The litmus test of Nitric Acid

1. Nitric acid does not turn the red litmus paper into blue, because the colour of the paper does not change when acid comes in contact with a red litmus paper.
2. If acid comes into contact with blue litmus paper, the colour of litmus paper changes into red.
3. Nitric acid is an acid, so it does not turn red litmus into the blue.

Therefore, due to the acidic behaviour of nitric acid, it does not turn red litmus blue. The above statement is false.
