Question

what is the pOH of a solution if the concentration of hydronium ionsis 8.9x10​-9

Answer 1

pOH of a solution = 5.95

Further explanation

Given

The concentration of hydronium ions : 8.9 x 10⁻⁹

Required

pOH

Solution

pOH = - log[OH]​

[H₃O⁺]= 8.9 x 10⁻⁹

pH = - log[H₃O⁺]

pH = 9 - log 8.9

pH = 8.05

pH + pOH = 14

pOH = 14-pH

pOH= 14-8.05

pOH = 5.95
