Chemistry - Redox Reactions Question with Solution | TestHub

An aq. solution of $0.5\mathrm{M}{\mathrm{KMnO}}_4$ is divided into two parts. One part of it requires 125 ml of 1.5 M aq. solution of oxalate ions in acidic medium, while another part requires 270 ml of 0.5 M aq. solution of iodide ions in neutral medium which are converted into ${\mathrm{I}}_2$ only. Calculate total volume ( mL ) of the initial ${\mathrm{KMnO}}_4$ solution.
