25.0 ml of a solution containing both

and

is titrated with 23.0 ml of a 0.0200 M

in dilute sulfuric acid. As a result, all of the

ions are oxidized to

ions.

Next, the solution is treated with Zn metal to convert all the

to

ions. Finally, the solution containing only the

ions requires 40.0 ml of the same

solution for oxidation to

.

Given that the net ionic equation is

, calculate the molar concentrations of the

and

ions in the original solution.

Please read forum rules.

This is simple stoichiometry.

Time you have spent formatting the question should be enough to solve it
