Eq wt of redox compounds =Molecular wt/Y
where
Y=the total change in oxidation no. in 1mole of compound(its imp 2 note )
redox compound=A_xB_Y
(I)If only 1 element say A is redox
1:If it enters into only one compound
+5            +3
A_----->      A+....
total change in ON=5-3=2=Y
2:If it enters into more than one compound
+7     +2 +0
2A---->A+A
Y=5+0/2=5/2 (take avg corresponding to each per mole change)
(II)If both elements are redox
1:If both are oxidized
+5 +3    +7 +4
A+B--->A+ B
Y=Total change in on fr A+Total change in on fr B
   =(7-5)+(4-3)=3
2:If one is oxidized and the other is reduced
Y cannot be found!!
3:If same element is oxidized and reduced (Disproportionation rxn)
+4     0 +5
A---->A+ A
1/Y=1/increase in on +1/decrease in on=1/(5-4)+1/(4-0)=1+1/4=5/4
Y=4/5

HOPE U FIND THEM USEFUL :):):):):)
