An aqueous solution at 25 °C has a pOH of 12.42. Calculate the pH. Round your answer to 2 decimal places

pH=1.58

Explanation:

As we know that

pH+pOH=14

Given that pOH=12.42

we get pH=14-pOH

or pH=14-12.42

or pH=1.58

The pH of a solution that has a pOH of 12.42 is 1.58

Explanation:

Step 1: Data given

At a temperature of 25.0 °C the pOH = 12.42

pH + pOH = 14

Step 2: Calculate the pH

pH + pOH = 14

pH = 14.00 - pOH

pH = 14.00 - 12.42

pH = 1.58

The pH of a solution that has a pOH of 12.42 is 1.58
