The Kw (the ionic product for water) at 60°C is 9.614·10⁻¹⁴ mol²/dm⁶.

Kw = [H ₃O⁺] · [OH⁻ ].

[ H₃O⁺] = [OH⁻] = √9.614·10⁻¹⁴ mol²/dm⁶.

[H ⁺] = [OH⁻] = 3.1·10⁻⁷ mol/L.

pH = - log[H ₃O⁺].

pH = - log (3.1·10⁻⁷ mol/L).

pH = 6.5; potential of hydrogen of neutral solution at 60°C.

pOH = - log [OH⁻].

pOH = 6.5.
