Question

A solution has a22.0*10^-6 H30^+ Calculate the OH^- and pH of this solution, be sure to show work.

Answer 1

pH= 4.66

OH^- = 4.55*10^-10

Step-by-step explanation:

So H3O^+ means the same thing as [H^+].

so pH= -log(22.0*10^-6)

pH= 4.66

To find [OH^-]

[H^+] [OH^-] = 1*10^-14

1*10^-14 / 22.0*10^-6 = 4.55*10^-10= OH^-
