what is the ph of a solution with a 2.20 × 10−8 m hydroxide ion concentration? 0.342 6.00 6.34 7.66

6.34

Explanation:

pH is the measure of acidity or alkalinity of a solution.

Acids have pH ranging from 1 to 6.9 and bases have pH ranging from 7.1 to 14.Neutral substances have pH of 7.

First we have to calculate the pOH.

Now we have to calculate the pH.

Therefore the pH of the solution will be 6.34.
