Answer:The pOH of the solution is 9.914
Explanation:
pH is given as the negative logarithm (base 10) of the hydronium ion concentration [H₃O⁺] that is
pH= - log [H₃O⁺]
Since we are given [H₃O⁺]=8.2 x 10⁻⁵,
pH=- log (8.2 x 10⁻⁵)
pH= 4.086
The pOH gives s the measurement of the concentration of OH− ions, Hence,
pH + pOH= 14
from the above calculation, we got pH=4.086
So
4.086 + pOH=14
pOH= 14 - 4.086
pOH= 9.914
The pOH of the solution is 9.914
