Question

please note that it has part A,B, & C

Balance each of the following redox reactions occurring in acidic solution. PbO_2 (s) + I^- (ag) rightarrow Pb^2+ (aq) + I_2 (s) Express your answer as a chemical equation. Identify all of the phases in your answer. SO_3^2- (aq) + MnO_4^- (aq) rightarrow SO_4^2- (aq) + Mn^2+ (aq) Express your answer as a chemical equation. Identify all of the phases in your answer. S_2O_3^2- (aq) + Cl_2(g) rightarrow SO_4^2- (ag) + Cl^- (aq) Express your answer as a chemical equation. Identify all of the phases in your answer.

Explanation / Answer

1. PbO2 + 2I- + 4HNO3 (l) ----> I2 (S) + Pb2+ (aq) + 2KNO3 (aq)+ 2H2O (l)

2. 3SO32- (aq )+ 2MnO4- (aq) + H2O(l) -----> 3SO42-(aq) + 2MnO2 (aq)+ 2OH- (aq)

3. S2O3 2 (aq) + 4 Cl2 (aq) + 5 H2O (l) 2 SO4 2 (aq) + 8 Cl (aq) + 10 H+ (aq)
