A) \[{{H}_{2}}S\]
B) \[{{H}_{2}}S{{O}_{4}}\]
C) \[S{{O}_{2}}\]
D) \[{{H}_{2}}S{{O}_{3}}\]
Correct Answer: A
Solution :
Oxidation number of sulphur in \[{{H}_{2}}S\],\[{{H}_{2}}S{{O}_{4}}\] \[{{H}_{2}}S{{O}_{3}}\] and \[S{{O}_{2}}\] are \[-2,\] \[+6\], \[+4\] and \[+4\]. Thus, \[{{H}_{2}}S\] can act only as reducing agent.You need to login to perform this action.
