(H30+) = 1x10^-6 M

Explanation:

Both pH and pOH have a relationship to belonging to the same aqueous solution: the expression of the Kwater (ionic product of the water Kw) is used:

1x 10-8 mol/L equals to1x10-8 M

(H3O+) x (OH-) = 1x10^-14

(H30+) x 1x 10^-8 = 1x10^-14

(H30+) = 1x10^-14/1x 10^-8

(H30+) = 1x10^-6 M
