A
Correct answer
Explanation
Pure water has a pH of 7, which is considered neutral on the pH scale (0-14). A pH of 7 means the concentration of hydrogen ions equals the concentration of hydroxide ions. pH values below 7 are acidic, while values above 7 are basic (alkaline). Pure water at 25°C has this neutral pH value.
AI explanation
To answer this question, we need to understand the concept of pH.
pH is a measure of the acidity or alkalinity of a solution. It is measured on a scale of 0 to 14, where 7 is considered neutral. Values below 7 indicate acidity, while values above 7 indicate alkalinity.
In the case of water, a pH of 7 is considered neutral. This means that water is neither acidic nor alkaline. Therefore, the correct answer is option A) 7.
