Directions: Questions are based on the following paragraph.
When ammonium vanadate is heated with oxalic add solution, a compound Z is formed. A sample of Z was titrated with KMnO4 solution in hot acidic solution. The resulting liquid was reduced with SO2, the excess SO2 boiled off, and the liquid again titrated with KMnO4. The ratio of the volumes of KMnO4 used in the two titrations was 5 : 1. KMnO4 oxidises all oxidation state of vanadium to Vanadium (+V) and SO2 reduces vanadium (+V) to vanadium (+IV). Read the above experiment and answer the following questions.

Explanation:
Oxidation state of vanadium in compound Z
- In order to determine the oxidation state of vanadium in the compound Z, we must understand the reactions involved in the experiment.
- When ammonium vanadate is heated with oxalic acid solution, compound Z is formed. This reaction leads to the formation of a compound in which vanadium is in a specific oxidation state.
- The subsequent titrations with KMnO4 and SO2 indicate the oxidation and reduction states of vanadium in the compound Z.
- KMnO4 oxidizes vanadium to the +V oxidation state, while SO2 reduces vanadium from +V to +IV oxidation state.
- The ratio of volumes of KMnO4 used in the two titrations is 5:1, indicating the specific oxidation state of vanadium in compound Z.
- Since KMnO4 oxidizes vanadium to +V state and the ratio of volumes used is 5:1, it implies that the oxidation state of vanadium in compound Z is 0 (zero).
- Therefore, the correct answer is option c) 0.
By analyzing the experimental procedure and understanding the oxidation and reduction reactions involved, we can determine that the oxidation state of vanadium in compound Z is 0.
