What is the pH of a neutral solution?

Explanation:
pH shows how acidic or basic a solution is by looking at the hydrogen ion concentration. A neutral solution has equal amounts of hydrogen ions (H+) and hydroxide ions (OH−). At standard room temperature, that balance corresponds to [H+] = [OH−] = 1.0 × 10^-7 M. Since pH is defined as the negative logarithm of the hydrogen ion concentration, pH = -log10([H+]) = -log10(1.0 × 10^-7) = 7. This is why pure water at about 25°C is considered neutral. Temperature can shift the exact neutral value slightly, but 7 is the conventional neutral value. Values below 7 are acidic, while values above 7 are basic. So 7 is the correct neutral pH; 6 would be acidic, 8 would be basic, and 0 would be extremely acidic.
