Question

Write equation for the reaction between k and acidified came in a4 identify the oxidizing and reducing agents

Answer 1

complex to be solved by trial and error within a reasonable amount of time. Consider the following reaction, for example.

3 Cu(s) + 8 HNO3(aq) -----> 3 Cu2+(aq) + 2 NO(g) + 6 NO3-(aq) + 4 H2O(l)

Other times, more than one equation can be written that seems to be balanced. The following are just a few of the balanced equations that can be written for the reaction between the permanganate ion and hydrogen peroxide, for example.

2 MnO4-(aq) + H2O2(aq) + 6 H+(aq) -----> 2 Mn2+(aq) + 3 O2(g) + 4 H2O(l)

2 MnO4-(aq) + 3 H2O2(aq) + 6 H+(aq) -----> 2 Mn2+(aq) + 4 O2(g) + 6 H2O(l)

2 MnO4-(aq) + 5 H2O2(aq) + 6 H+(aq) -----> 2 Mn2+(aq) + 5 O2(g) + 8 H2O(l)

2 MnO4-(aq) + 7 H2O2(aq) + 6 H+(aq) -----> 2 Mn2+(aq) + 6 O2(g) + 10 H2O(l)

Equations such as these have to be balanced by a more systematic approach than trial and error.
