b. 4.00 x 10 -11
c. 5.00 x 10 -12
d. 4.00 x 10 -12
Solution
Hydroxide ion concentration, [OH -
] = 2.50 x 10 -3
M
We know that, [H +
] [OH -
] = 1 x 10 -14
or, [H +
] = (1 x 10 -14
) / [OH -
] = (1 x 10 -14
) / (2.50 x 10 -3
) = 4 x 10 -12

- 1. Calculate the H + concentration in an aqueous solution that contains 2.50 x 10 -3 M hydroxide ion. 4.00 x 10 -10 4.00 x 10 -11 5.00 x 10 -12 4.00 x 10 -12 a. 4.00 x 10 -10 b. 4.00 x 10 -11 c. 5.00 x 10 -12 d. 4.00 x 10 -12 Solution Hydroxide ion concentration, [OH - ] = 2.50 x 10 -3 M We know that, [H + ] [OH - ] = 1 x 10 -14 or, [H + ] = (1 x 10 -14 ) / [OH - ] = (1 x 10 -14 ) / (2.50 x 10 -3 ) = 4 x 10 -12 M
