Demarion Maxwell · Answer 1

The correct answer is B has a neutral pH

Explanation:

we all know that acid converts blue litmus to red on the other hand base converts red litmus paper to blue.

According to the question the blue litmus paper does not change its colour or it stays blue that means the pH of solution is neutral or7 which prevent the colour change of the litmus paper.

If the solution was acidic then the blue litmus paper changes into red.
