To complete the chemical equation for the reaction of dichromate ion (\(Cr_2O_7^{2-}\)) with hydrogen ions (\(H^+\)) and iodide ions (\(I^-\)), we can follow these steps: ### Step 1: Identify the Oxidation and Reduction - The dichromate ion (\(Cr_2O_7^{2-}\)) is a well-known oxidizing agent. In this reaction, it will oxidize iodide ions (\(I^-\)) to iodine (\(I_2\)). - The iodide ion (\(I^-\)) is in the -1 oxidation state and will be oxidized to iodine (\(I_2\)), which is in the 0 oxidation state. - Simultaneously, the dichromate ion will be reduced to chromium ions (\(Cr^{3+}\)). ### Step 2: Write the Half-Reactions ...
