A) +2
B) +4
C) + 6
D) +7
Correct Answer: C
Solution :
The chemical structure of \[{{\text{H}}_{\text{2}}}{{\text{S}}_{\text{2}}}{{\text{O}}_{\text{8}}}\]is as follows: \[H-O-\underset{O}{\overset{O}{\mathop{\underset{||}{\overset{|\,|}{\mathop{S}}}\,}}}\,-O-O-\underset{O}{\overset{O}{\mathop{\underset{|\,|}{\overset{|\,|}{\mathop{S}}}\,}}}\,-O-H\] Let the oxidation number of is \['x'\]| \[2\times (+1)\] | \[+2\times x\] | \[+6\times (-2)\] | \[+2\times (-1)\] | \[=0\] |
| For H | For S | For O | For(O-O) |
