What would the pOH of a solution be if the pH is 9.4
Alika [10]
<h2>Answer:</h2>

pOH = 4.6

<h2>Explanations:</h2>

The sum of pH and pOH of a solution is 14as shown:

pH+pOH=14

Given the following parameter

pH = 9.4

Substitute the given parameters into the formula to have:

Hence the pOH of the solution of pH of 9.4 is 4.6
