Question

The pH value for pure water ($H_{2}O$) is 7.0. What do you understand by this?

• A. Pure water is acidic.
• B. Pure water is basic.
• C. Pure water is neither acidic nor basic but neutral.
• D. Pure water turns red litmus paper to blue.

Answer 1

The correct option is C Pure water is neither acidic nor basic but neutral.

We know, for acidic subsatnces, the pH range is from 0 - 7, for basic subsatnces, the pH range is from 7 - 14 and for neutral substances, the pH is around 7.
It is given that, the pH for pure water is 7. This means that, pure water is neither acidic nor basic but neutral.
