Write the O.N. of all the atoms in the following well known oxidants: (i)\[KMn{{O}_{4}}\]        (ii)\[{{K}_{2}}C{{r}_{2}}{{O}_{7}}\]            (iii)\[KCl{{O}_{4}}\]

Answer:

                (i) \[KMn{{O}_{4}}\]: \[K(+1);\,Mn\,(+7)\,;\,\,O(-2)\]                 (ii) \[{{K}_{2}}C{{r}_{2}}{{O}_{7}}\]: \[K(+1);\,Cr\,(+6)\,;\,O\,(-2)\]                 (iii) \[KCl{{O}_{4}}\]: \[K(+1)\,;\,Cl\,(+7);\,O\,(-2)\]
