What is the pOH of a solution with [H3O+] = 8.2 x 10-5M?

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

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
