Question

pH value of pure water is:

• A. 0
• B. 1
• C. 7
• D. 10

Hint:

Water is neutral at a pH of 7, meaning it is neither acidic nor alkaline.

Answer 1

The Correct Option is C

Step 1: Understand the pH scale. The pH scale measures the acidity or basicity of a solution,
where:
- A pH of 7 indicates a neutral solution. - A pH below 7 indicates an acidic solution. - A pH above 7 indicates a basic (alkaline) solution.
Step 2: Analyze the pH of pure water. Pure water is neutral, with a pH of exactly 7 at 25°C.
Step 3: Conclude. Thus, the pH value of pure water is \(
7 \).
