Balance each of the following redox reactions occurring in acidic solution. Cr2O

Question

Balance each of the following redox reactions occurring in acidic solution. Cr2O72-(aq) + Cu+ (aq) rightarrow Cr3+(aq) + Cu2+(aq) Express your answer as a chemical equation. Identify all of the phases in your answer. IO3-(aq) + H2SO3(aq) rightarrow I2(aq) + SO42-(aq) Express your answer as a chemical equation. Identify all of the phases in your answer. MnO2(s) + Cu(s) rightarrow Cu2+(aq) + Mn2+(aq) Express your answer as a chemical equation. Identify all of the phases in your answer.

Explanation / Answer

part a: Cr2O7{2-} + 14 H{+} + 3 Cu ? 2 Cr{+3} + 7 H2O + 3 Cu{+2} only one phase part b: 5H2SO3(aq) + 2IO3^-(aq)----> 5SO4^2-(aq) + 8H+(aq) + I2(aq) + H2O(l)
