Answer to Question #330577 in General Chemistry for Ivan Ackerman

General Chemistry

Question #330577

Determine the [H+] , pH, and pOH of a solution with an [OH−] of 7.2×10−8 M at 25 °C.

[H+]=

pH=

pOH=

Expert's answer

pOH = -lg[OH⁻] = -lg(7.2×10^-8) = 7.14

pH = 14 - pOH = 14 - 7.14 = 6.86

[H⁺] = 10^-pH = 10^-6.86 = 1.38×10^-7 M
