Question

Determine the [H+] of a solution that has a [OH-] of 6.25*10-12. (Enter answer in expanded format not scientific notation)

Answer 1

answer and explanation

we are given the [OH] concentration as 6.25*10-12

and we know that

[H+][OH-] = 1.0*10^-14

an so using this relationship we can determine the [H+]

[H+][6.25*10-12] = 1.0*10-14

[H+] = 0.0016M
