4.9 g of K2Cr2O7 is taken to prepare 0.1 L of the solution. In acidic medium 5 mL of this solution is further taken to oxidize Sn2+ ion into Sn4+ ion. If Sn4+ so produced is used in 2nd reaction to prepare Fe3+ ion from Fe2+, then the millimoles of Fe3+ ion formed will be:(Assume all other components are in sufficient amount) [Molar mass of K2Cr2O7=294 g mol−1]

Answer» $4.9 g$ of $K_{2} C r_{2} O_{7}$ is taken to prepare $0.1 L$ of the solution. In acidic medium $5 mL$ of this solution is further taken to oxidize $S n^{2 +}$ ion into $S n^{4 +}$ ion. If $S n^{4 +}$ so produced is used in $2^{n d}$ reaction to prepare $F e^{3 +}$ ion from $F e^{2 +,}$ then the millimoles of $F e^{3 +}$ ion formed will be: (Assume all other components are in sufficient amount) [Molar mass of $K_{2} C r_{2} O_{7} = 294 {g mol}^{- 1}]$
