Assertion : Oxidation number of \(\mathrm{S}\) in \(\mathrm{HSO}_{3}^{-}\)is +4 . Reason : Sulphur is in different oxidation states in different compounds.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Let oxidation number of \(\mathrm{S}\) in \(\mathrm{HSO}_{3}^{-}\)be \(\mathrm{x}\). \(\begin{gathered}+1+\mathrm{x}+3(-2)=-1 \\\therefore \mathrm{x}=+4\end{gathered}\) Sulphur can show variable O.N. from \((- 2)\) to \((+ 6)\) in different compounds So the option (2) is correct.

What is the oxidation number of As in \(\mathrm{\mathrm{H}_{3} \mathrm{AsO}_{3}}\) ?
1 \( + 4\)
2 \( + 3\)
3 \({\rm{ - 3}}\)
4 \( + 2\)
Explanation:
Oxidation number of \(\mathrm{\mathrm{As}=+3}\). \(\mathrm{\mathrm{H}_{3} \mathrm{AsO}_{3}}\) Let oxidation state of \(\mathrm{\mathrm{As}=\mathrm{x}}\) We know that, oxidation number of \(\mathrm{\mathrm{H}=+1, \mathrm{O}}\) \(\mathrm{=-2}\) Putting the values in formula, \(({\rm{1}}){\rm{3 + x + }}({\rm{ - 2}}){\rm{3 = 0}}\) \({\rm{3 + x - 6 = 0}} \Rightarrow {\rm{x = + 3}}\)
