A) dithionous acid
B) sulphurous acid
C) thionous acid
D) phyrosulphuric acid
Correct Answer: A
Solution :
\[\underset{\text{Dithionous}\,\text{acid}}{\mathop{H-O-\overset{O}{\mathop{\overset{||}{\mathop{S}}\,}}\,-\overset{O}{\mathop{\overset{||}{\mathop{S}}\,}}\,-O-H}}\,\] Let oxidation state of sulphur is \[x.\] \[2\times 1+4\times (-2)+2x=0\] \[2-8+2x=0\] \[2x=+\,6\] \[x=+\,3\]You need to login to perform this action.
