pH neutral corresponds to which value?

Explanation:
On the pH scale, neutrality means there are equal amounts of hydrogen ions and hydroxide ions. This condition yields a pH of 7 at standard room temperature because pH is defined as the negative logarithm of the hydrogen-ion concentration, pH = -log10[H+]. In pure water at 25°C, [H+] is 1.0 x 10^-7 M, giving pH = 7. Values below 7 indicate acidity, while values above 7 indicate basicity. So the neutral value is 7.
