Question

A solution turns red litmus into blue. The pH value of this solution would be:

• A. 7
• B. More than 7
• C. Less than 7
• D. None of these

Hint:

Always remember: Acids (\(<7\)), Neutral (=7), Bases (>7).

Answer 1

The Correct Option is B

Step 1: Litmus test.
Red litmus turning blue indicates that the solution is basic.
Step 2: pH range.
Acidic solutions: \(pH<7\)
Neutral solutions: \(pH = 7\)
Basic solutions: \(pH>7\).
Step 3: Conclusion.
Since the solution is basic, its pH is more than 7.
