Answer: The pOH of the nitric acid solution is 10.75.

Explanation:

The pH of nitric acid solution used by chemist ,[tex]HNO_3[/tex] = 3.75

The sum of pH and pOH is always equal to 14 at room temperature.

[tex]pH+pOH=14[/tex]

pOH =14 - pH = 14 - 3.72 = 10.75

Hence, the pOH of the nitric acid solution is 10.75.
