Question

If the hydrogen ion concentration, [H+], in a solution is 2.65 x 10-2 M, what is [OH-]?

Answer 1

Answer:

A

Explanation:

Answer 2

If the hydrogen ion concentration, [H+], in a solution is 2.65 x 10-2 M, then [OH-] will be 3.77x 10-13 M

What is hydrogen ion concentration?

Hydrogen ion concentration is the factor that determines the acidity of water.

Given,

$H^+=2.65*10^-^2$

To find the concentration of [OH-].

It is known that,

$[H^+]*[OH^-]=1*10^-^1^4$

$OH^-=\frac{1*10^-^1^4}{2.65*10^-^2}$

$OH^-=3.77*10^-^1^3$

Thus, the correct answer is 3.77x 10-13 M.
