1.	15.0 mL of 0.12 M KMnO_(4) solution are required to oxidise 20.0 mL of FeSO_(4) solution in aicdic medium what is the concentration of FeSO_(4) solution ?
Answer» Solution :The balaced chemcial equation for the REDOX reaction is `2KMnO_(4)+10FeSO_(4)+8H_(2)SO_(4)rarrK_(2)SO_(4)+2MnSO_(4)+5Fe_(2)(SO_(4)^(3)+8H_(2)O)` APPLYING molarity eqautin to the above redox reaction `=(15xx0.12)/(2)KmnO_(4)=(20xxM_(1))/(10)(FeSO_(4)) or M_(1)=(15xx0.12xx10)/(2xx20)=0.45`
