This is the Best answer for Calculate H+ : a solution in which [OH -] is 100 times greater than [H+]?
In a neutral solution;
[H+] = [OH-] = 1x10^-7 M
Since [OH-] greater than [H+], the solution is basic.
In all solutions, whether neutral, or acidic or basic,
Kwater should be satisfied.
Kw = [H+][OH-] = 1x10^-14
Since [OH-] = 100[H+]
Kw = [H+] x 100 [H+] = 1x10^-14
[H+]^2 = 1x10^-14 / 100 = 1x10^-16
[H+] = 1x10^-8 M
[OH-] = Kw / [H+] = 1x10^-14 / 1x10^-8 = 1x10^-6 which is 100 times greater than 1x10^-8
