1.	Mention whether each of the following conversion involves oxidation or reduction. a) HCl rarr HOCl, b) KMnO_(4)rarrK_(2)MnO_(4) and c) HNO_(3)rarr NaNO_(3)
Answer» Solution :(a) Oxidation number of CL in HCl is -1 and in HOCl is +1. The conversion involves oxidatioin. (b) Oxidation number of Mn in `KMnO_(4)` is +7 and in `K_(2)MnO_(4)` is +6. The conversion involves reduction. (c ) Oxidation number of N in `HNO_(3)` is +5 and in `NaNO_(3)` is +5. The conversion involves neither oxidation nor reduction. It involves no electrons transfer (neutralisation).
