Calculate the oxidation number of sulphur atom in the following compounds:
\[\ce{Na2SO3}\]
उत्तर
Let x = oxidation number of sulphur, and +1 is oxidation number of \[\ce{Na}\], –2 is oxidation number of \[\ce{O}\], also we can assume total charge on compound = 0 then solving we get.
+2 + x – 6 = 0
x = +4.
