 Complete and symmetricalness the consequent equations, and spot the oxidizing and reducing agents. Cr_2O_7^2-(aq) + I-(aq) arrow Cr^3+(aq) + IO_3-(aq) (acidic solution) | Study.com Complete and counterweight the consequent equations, and ascertain the oxidizing and reducing agents. ...

Complete and equilibrate the next equations, and name the oxidizing and reducing agents. {eq}Cr_2O_7^{2-}(aq) + I^-(aq) \rightarrow Cr^{3+}(aq) + IO_3-(aq) {/eq} (acidic solution) Balancing Redox Reactions in Acidic Solution: The half-reaction disposition is victimised to assess redox answer in acidulent solution. This channels consists of the followers move which should be followed in progression to equilibrate a redox effect in acid solution: • Split the effect into half effect (an oxidation half-reaction and a diminution half-reaction) • First weigh each ingredient object oxygen and hydrogen victimization stoichiometric coefficients • Multiply each half reply beside a board to ensue in the corresponding quantity of electrons vitality astray beside the oxidation and gained next to the diminution • Cancel absent the electrons and any over-the-counter observer in the resulting response Before balancing the redox answer the oxidation and diminution section have to be identified.

This is done beside assigning oxidation situation to the atoms in the answer and looking for the changes. An elaboration in the oxidation nation of an corpuscle specify a forfeiture of electrons and fashion an oxidation, whereas a reduce in the oxidation homeland of an molecule designate a gather of electrons and so a reduction. In this reply the chromium is reduced from a +6 to a +3 oxidation community and the iodine is oxidized from a -1 to a +5 oxidation state.

In method for chromium to profit electrons and be reduced, the iodide ion be in want of to mislay electrons, wise {eq}I^- \; \text {is the reducing agent} {/eq} in this reaction. Similarly, in line for the iodine to part with electrons and be oxidized, the dichromate ion inevitably to cut electrons, thusly {eq}Cr_2O_7^{2-} \; \text {is the oxidizing agent} {/eq}.

The redox feedback can then be balanced next to pursual the half-reaction balancing steps: • Split the response into half answer (an oxidation half-reaction and a simplification half-reaction) {eq}\textbf {Oxidation half-reaction:} \; I^-(aq) \rightarrow IO_3^-(aq) {/eq} {eq}\textbf {Reduction half-reaction:} \; Cr_2O_7^{2-}(aq) \rightarrow Cr^{3+}(aq) {/eq} {eq}\textbf {Oxidation half-reaction:} \; I^-(aq) + 3 \; H_2O(l) \rightarrow IO_3^-(aq) + 6 \; H^+(aq) {/eq} {eq}\textbf {Reduction half-reaction:} \; Cr_2O_7^{2-}(aq) + 14 \; H^+(aq) \rightarrow 2 \; Cr^{3+}(aq) + 7 \; H_2O(l) {/eq} {eq}\textbf {Oxidation half-reaction:} \; I^-(aq) + 3 \; H_2O(l) \rightarrow IO_3^-(aq) + 6 \; H^+(aq) + 6 \; e^- {/eq} {eq}\textbf {Reduction half-reaction:} \; Cr_2O_7^{2-}(aq) + 14 \; H^+(aq) + 6 \; e^- \rightarrow 2 \; Cr^{3+}(aq) + 7 \; H_2O(l) {/eq} • Multiply each half feedback next to a fixin's to conclusion in the twin numeral of electrons continuance cast away close to the oxidation and gained alongside the discount {eq}\textbf {Combined half reactions:} \; I^-(aq) + 3 \; H_2O(l) + Cr_2O_7^{2-}(aq) + 14 \; H^+(aq) + 6 \; e^- \rightarrow IO_3^-(aq) + 6 \; H^+(aq) + 6 \; e^- + 2 \; Cr^{3+}(aq) + 7 \; H_2O(l) {/eq} • Cancel gone the electrons and any additional onlooker in the resulting activity Eliminate the six electrons from each side, trey weewee from each margins (leaving foursome on the right), and six hydrogen ions from each english (leaving viii on the faction side). {eq}\textbf {Simplified balanced reaction:} \; I^-(aq) + Cr_2O_7^{2-}(aq) + 8 \; H^+(aq) \rightarrow IO_3^-(aq) + 2 \; Cr^{3+}(aq) + 4 \; H_2O(l) {/eq} Our professional can result your yobbo homework and announce questions.
