The pH value that is neutral is a value of which number?

Explanation:
Neutral on the pH scale means the hydrogen ion concentration equals the hydroxide ion concentration. In pure water at standard room temperature, this balance occurs at a pH of 7, since [H+] = [OH-] = 1×10^-7 M and pH = -log10[H+]. Numbers below 7 indicate acidity (more H+), while numbers above 7 indicate basicity (more OH-). Values like 0 or 3 are strongly acidic, and 14 is strongly basic. Therefore, the neutral value is 7.
