As an oxidizing agent to convert ferrous ions $(Fe^{2+})$ to ferric ions $(Fe^{3+})$ in acidic medium

(A) Potassium dichromate $(K_2Cr_2O_7)$ is a powerful oxidizing agent in acidic medium. It is widely used in volumetric analysis to oxidize ferrous ions $(Fe^{2+})$ to ferric ions $(Fe^{3+})$ according to the reaction: $Cr_2O_7^{2-} + 14H^+ + 6Fe^{2+} \rightarrow 2Cr^{3+} + 6Fe^{3+} + 7H_2O$.
