Neutral litmus solution have _ _ _ _ _ _ _?(A) No effect of acidic solution(B) No effect of alkaline solution(C) Both A and B(D) None of these

To solve the question about neutral litmus solution, let's first understand what litmus is and how it behaves in different conditions:

Litmus is a pH indicator derived from lichens. It is commonly used to test whether a solution is acidic or alkaline (basic).
Neutral litmus solution refers to a solution that has a pH of around 7, which is neither acidic (pH < 7) nor alkaline (pH > 7).
Explanation of Options:
(A) No effect of acidic solution:

If you add an acidic solution (like hydrochloric acid) to neutral litmus, the litmus will change color to red, indicating acidity. Therefore, this statement is false.
(B) No effect of alkaline solution:

If you add an alkaline solution (like sodium hydroxide) to neutral litmus, the litmus will change color to blue, indicating alkalinity. Thus, this statement is also false.
(C) Both A and B:

Since both A and B are false, this option is also false.
(D) None of these:

Given that both A and B are incorrect, this is the correct option.
Conclusion:
The correct answer is (D) None of these. Neutral litmus solution will change color when introduced to either an acidic or alkaline solution.
