Question

Write balanced net ionic equations for the following reactions in basic solution. Express your answer as a chemical equation. Identify all of the phases in your answer. a) S2O3 2-(aq) + I2(aq)-->S4O6 2-(aq) + I-(aq) b) Mn 2+(aq) + H2O2(aq)-->MnO2(s) + H2O(l) C) Zn(s) + NO3-(aq)-->NH3(aq) + Zn(OH4) 2-(aq) d) Bi(OH)3(s) + Sn(OH)3 -(aq)-->Bi(s) + Sn(OH)6 2-(aq) Write balanced net ionic equations for the following reactions in basic solution. Express your answer as a chemical equation. Identify all of the phases in your answer. a) S2O3 2-(aq) + I2(aq)-->S4O6 2-(aq) + I-(aq) b) Mn 2+(aq) + H2O2(aq)-->MnO2(s) + H2O(l) C) Zn(s) + NO3-(aq)-->NH3(aq) + Zn(OH4) 2-(aq) d) Bi(OH)3(s) + Sn(OH)3 -(aq)-->Bi(s) + Sn(OH)6 2-(aq)

Explanation / Answer

a) 2*S2O3 2-(aq) + 1*I2(aq)-->1*S4O6 2-(aq) + 2*I-(aq)

b) Mn 2+(aq) + H2O2(aq) + 2*OH- -->MnO2(s) + 2*H2O(l)

c) 4Zn + NO3- + 7OH- + 6H2O --> 4Zn(OH)4^2- + NH3(aq)

d) 2Bi(OH)3(s) + 3Sn(OH)3^- + 3OH- --> 2Bi(s) + 3Sn(OH)6^2-
