The pH of a basic solution is 9.77. What is [OH⁻]?

uysha [10]

The [OH⁻] of the solution is 5.37×10⁵ M.

This is the negative logarithm to base 10 of hydroxy ion [OH⁻] concentration.

To calculate the hydroxy ion [OH⁻] concentration we use the formula below.

Note:

pH+pOH = 14

pOH = 14-pH
pOH = 14-9.77
pOH = 4.27

Formula:

[OH⁻] = 1/ $10^{pOH}$ ................. Equation 1

Given:

pOH = 4.27

Substitute the value into equation 1

[OH⁻] = 1/ $10^{4.27}$
[OH⁻] = 5.37×10⁵

Hence, The [OH⁻] of the solution is 5.37×10⁵ M.
