Consider the table of the standard electrode Reduction half-reaction Au³+ (aq) + 3e → Au(s) 103¯(aq) + 6H+ (aq) +5e¯ → ⁄12(aq) + 3H₂O(1) 2H+ (aq) + 2e → H₂(g) Cr³+ (aq) + 3e →→ Cr(s) potentials at 25 °C: & medlemsta le ama o MALKISANAKIN DE HEREN KALAN KAK MEN NIE E° (V) 1.50 1.20 0 -0.73
Part A Identify whether Au or Cr or both or neither will dissolve in 1 M HIO₂. Only Au will dissolve. Only Cr will dissolve. Both Au and Cr will dissolve. ONeither Au nor Cr will dissolve. O Previous Answers ✓ Correct HIO, oxidizes metals through the following reduction hall-reaction: IO (aq) + 6H (aq) +5e 12(aq) + 3H₂O(1) Because this half-reaction is above the reduction of H in the table, HIOs can oxidize some metals (for example, copper or silver) that cannot be oxidized by HCl. In general, the metals with reduction half-reactions listed below the reduction of IO, to Ia in the table dissolve in HIO3, whereas the metals listed above it do not. Therefore, Au (which has a reduction potential of 1.50 V) will not be oxidized, but Cr (which has a reduction potential of -0.73 V) will be oxidized by both HCl and HIO,.
Part B Enter a balanced redox equation for the reaction that occurs. Express your answer as a balanced net lonic equation including phases. | ΑΣΦ + 610 (aq) +36Hf(aq) + 10Cr(aq)→31, (aq) + 10Cr¹ (aq) + 13H, O(1) ? 3 A chemical reaction does not occur for this question.
