What is the [H3O+] in a solution with [OH-] = 1.0 x 10-12 M?

1.0 x 10-2 M

1.0 x 10-8M

1.0 x 10-12M

1.0 x 102 M

The concentration of hydronium ions in the solution is M.

Explanation:

Concentration of hydroxide ions concentration =

The pOH if the solution is given by :

pOH = 12

The relation between pH and OH is given by : pH + pOH = 14

pH = 14 - pOH

pH =14 - 12 = 2

The pH of the solution isgiven by :

The concentration of hydronium ions in the solution is M.
