A) \[MnS{{O}_{4}}\]
B) \[M{{n}_{2}}{{\text{O}}_{7}}\]
C) \[Mn{{O}_{2}}\]
D) \[M{{n}_{2}}{{\text{O}}_{3}}\]
Correct Answer: B
Solution :
[b] \[KMn{{O}_{4}}\] reacts with \[{{H}_{2}}S{{O}_{4}}\] to form \[M{{n}_{2}}{{O}_{7}}\] which is highly explosive substance. \[2KMn{{O}_{4}}+{{H}_{2}}S{{O}_{4}}\xrightarrow{{}}\] \[{{K}_{2}}S{{O}_{4}}+M{{n}_{2}}{{O}_{7}}+{{H}_{2}}O\]
