Question

A solution has a [H3O+] of 1x 10-5 M. What is the [OH-] of the solution? (5 points)
9M
14M
1x 10-'M
1x 10-14M

Answer 1

Answer:

1x10^–9 M

Explanation:

From the question given,

Concentration of hydronium ion, [H3O+] = 1x10^-5 M.

Concentration of Hydroxide ion, [OH-] =..?

The concentration of the hydroxide ion, [OH-] can be obtained as follow:

[H3O+] x [OH-] = 1x10^–14

1x10^-5 M x [OH-] = 1x10^–14

Divide both side by 1x10^-5

[OH-] = 1x10^–14 / 1x10^-5

[OH-] = 1x10^–9 M

Answer 2

The  [OH⁻] concentration of the solution is  1 * 10⁻⁹M.

What is pH value ?

pH value is the measure of the acidity and alkalinity of a solution , The pH value has the range of 0 to 14, where 0-7 is the range for acid , 7 is for neutral solution , 7-14 is for alkaline solution.

[H3O⁺] = 1* 10⁻⁵ M

We can calculate the value of OH⁻ concentration  by using the formula

[H⁺][OH⁻] = 1* 10⁻¹⁴

1* 10⁻⁵  * [OH⁻] = 1* 10⁻¹⁴

[OH⁻] = 1 * 10⁻⁹

Therefore the  [OH⁻] concentration is  1 * 10⁻⁹M .
