Question

6. In the balanced redox equation: 8H+ + 6Cl- + Sn + 4NO3 -1 --> SnCl6 -2 + 4NO2 + 4H2O the reducing agent is

a) H +
b) Cl
c) Sn
d) NO3 -1
e) SnCl6 -2

Answer 1

Answer: The oxidizing agent in the given reaction will be NO3 -1 ion.

Reactant side:

Oxidation state of hydrogen = +1

Oxidation state of oxygen = -2

Oxidation state of Tin = 0

Oxidation state of chlorine = -1

Oxidation state of nitrogen = +5

Product side:

Oxidation state of hydrogen = +1

Oxidation state of oxygen = -2

Oxidation state of Tin = +6

Oxidation state of chlorine = -1

Oxidation state of nitrogen = +4
