A pH neutral is achieved at which value?

A pH neutral is achieved at which value?

• A. 6
• B. 7
• C. 8
• D. 9

Answer: (B)

Neutral pH means the solution is neither acidic nor basic. On the pH scale, that balance occurs at 7, where hydrogen ions and hydroxide ions are present in equal amounts. At room temperature, pure water has [H+] and [OH−] both about 1.0×10−7 M, giving pH 7. Values below 7 are considered acidic, while values above 7 are basic. So 7 is the neutral point, whereas 6 is acidic and 8 or 9 are basic.
