Question

If the concentration of [H*) ion in a solution is 3.5 x 10-4 N, then determine the pOH
of the solution :-

(1) 3.46
(2) 10.54
(3) 14
(4) 7​

Answer 1

Answer:

To calculate the pOH of a solution you need to know the concentration of the hydroxide ion in moles per liter (molarity). The pOH is then calculated using the expression: pOH = - log [OH-]

Explanation:

To find the pOH, simply subtract the pH from 14. In order to calculate the pOH, take the negative log of the hydroxide ion concentration. To find the pH, simply subtract pOH from 14.

10.54 is the answer
