Question

What will be the outcome of putting litmus paper into bleach?

a. red paper turns blue, blue paper turns red
b. red paper does not change, blue paper turns red
c. red paper turns blue, blue paper does not change
d. red paper does not change, blue paper does not change

Answer 1

The correct option is c

Step-by-step explanation:

The major ingredient in household bleach is sodium hypochlorite (NaClO). This compound is a base and the bleach solution assumes this alkalinity status.

A base is a substance that produces hydroxyl/hydroxide ion (OH⁻) as the only negative ion when dissolved in water. The pH of a base is between 7 to 14. One of the major properties of base is that it turns red litmus paper blue and it has no effect on blue litmus paper.

Answer 2

The correct answer is option C. The outcome of putting litmus paper into bleach would be that red paper turns blue, blue paper does not change. Domestic bleach is a strong base it typically has a pH of 11 to 13. So when testing for pH, it would really go with the basic characteristics.
