Definition of pH

In chemistry, pH is a logarithmic measure of the concentration of hydrogen ions in an aqueous solution

Definition of log in (pH = –log [H+])

Log is logarithm of base 10

Definition of [H+] in (pH = –log [H+])

[H+] is the concentration of hydrogen ions in mol dm–3 of the solution
