Introduction
The reaction involving the fusion of XO2 with alkali metal hydroxide and an oxidizing agent like KNO3 leads to a dark green product that subsequently disproportions in acidic conditions, yielding a dark purple solution. Here, we will identify X as Manganese (Mn).
Reaction Overview
- XO2 represents a metal oxide, where X is the metal.
- In this case, we are considering manganese dioxide (MnO2).
Formation of Dark Green Product
- When MnO2 is fused with alkali metal hydroxide in the presence of KNO3, a complex manganese species is formed.
- This dark green product typically contains manganese in a higher oxidation state, possibly as a manganate ion (MnO4^2-).
Disproportionation Reaction
- In acidic solutions, the dark green manganate undergoes disproportionation:
- 2 MnO4^2- → MnO4^- (purple) + MnO2 (brown).
- The dark purple solution formed is due to the presence of permanganate ions (MnO4^-), which are well-known for their deep purple color.
Conclusion
- Based on these reactions, the metal X that leads to the formation of such products is indeed Manganese (Mn).
- Therefore, the correct answer is option 'A'.
This process highlights the intriguing chemistry of manganese and its ability to undergo oxidation and reduction reactions, exemplifying its versatile oxidation states.
