Answer:
D 8.8
Explanation:
To solve this question you must know that, using the kw equation:
Kw = 1x10⁻¹⁴ = [H⁺] [OH⁻]
-log 1x10⁻¹⁴ = -log ([H⁺] [OH⁻])
14= -log [H⁺] + -log [OH⁻]
As pH = -log[H⁺] and pOH = -log [OH⁻]
we can obtain the equation:
pH = 14 - pOH
As the pOH of the solution is 5.2:
pH = 14 - 5.2
pH = 8.8
Right option is:
