What is the pOH of a solution of HNO3 that has [OH– ] = 9. 50 × 10–9 M?.

Sagot :

8.022 is the value of pOH of the HNO₃ solution.

How pOH can be calculated?

pOH of the HNO₃ solution can be calculated as:

pOH = -log [OH⁻], where

[OH⁻] = concentration of hydroxyl ion = 9. 50 × 10⁻⁹ M

Putting this value in the above equation, we get

pOH = -log ( 9. 50 × 10⁻⁹)

pOH = - (- 8.022) = 8.022

Hence, pOH of the HNO₃ solution is 8.022.
