Transition metal

Titration of a sample conatining 0.0010mol of vanadium, VOCl_x , required 20.0 cm³ of 0.020 mol dm^-3 KMnO₄ (aq) for its complete oxidation in acidic solution.

1) Using E^o data, predict the final oxidation state of the vanadium after titration.
2) Use the titration data given to calculate the change in oxidation number undergone by the vanadium during the titration.
3) Hence, deduce a value for x in VOCl_x.


I do not know where to start. Could someone please go through this question step by step?

You can use a data booklet.

Then use one to see which oxidation states of vanadium can be oxidised by manganate(VII) ions and which cannot ....
