Why pH lies between 0 to 14 only

Answer Posted / bhavin prajapati

pH is the concentration hydrogen ion in solution. pH range is 0 to 14, it's only for water (aqueous media), because when water dissolution concent is 1*10^-14, so OH- is 1 moler in solution that time H+ is 1*10^-14 and pH= 0, and H+ is 1 molar in solution that time OH- is 1*10^+14 and pH= 14, so water is universal solvent and for that pH range is 0 to 14 accepted by IUPAC world wide.
