MCQ
It is found that V forms a double salt isomorphous with Mohr's salt. The oxidation number of V in this compound is_________.
- A3
- B+2
- C+4
- D−4
✓
Answer
- +2
Explanation:
Double salt of V isomorphous with Mohr's salt is (NH4) 2V(SO4)2. 6H2O.
When double salt dissolves in water it dissociates to give NH4 + ,V+2 and SO4−2.
So oxidation state of vanadium is +2.
