Question

Calculate the pOH of a solution with [OH⁻] = 1.2 x 10⁻²

Answer 1

The pOH of a solution with a hydroxide ion concentration of 1.2 x 10^-2 M is approximately 1.92, calculated using the pOH formula pOH = -log([OH^-]).

Step-by-step explanation:

To calculate the pOH of a solution with a given hydroxide ion concentration ([OH−]), we use the formula:

pOH = −log([OH−])

In this case, the concentration of hydroxide ions is 1.2 x 10−2 M.

Therefore, the pOH calculation would be as follows:

pOH = −log(1.2 x 10−2)

The pOH value calculated from this concentration of hydroxide ions is approximately 1.92.
