At 25 °C, what is the hydroxide ion concentration, [OH−] , in an aqueous solution with a hydrogen ion concentration of [H+]=4.3×10−6 M?

Question

At  25   °C, what is the hydroxide ion concentration,  [OH−]  , in an aqueous solution with a hydrogen ion concentration of  [H+]=4.3×10−6   M?

Louie H. · Accepted Answer

The [OH-] concentration would be as follows:[H3O+][OH-]=1*10^-14[OH-]=(1*10^-14)/(4.3*10^-6) = 2.3*10^-9 M
