Given the balanced ionic equation:3Pb2+ + 2Cr ==> 3Pb + 2Cr3+
What is the number of moles of electrons gained by 3.0 moles of lead ions?
(1) 5.0 mol (3)3.0 mol
(2) 2.0 mol (4) 6.0mol

Answers

Answer : The correct option is, (4) 6.0 mol

Explanation :

The given balanced ionic equation is,

3Pb^(2+)+2Cr\rightarrow 3Pb+2Cr^(3+)

In this reaction, lead undergoes reduction and chromium undergoes oxidation.

  • Oxidation reaction : It is the reaction in which a substance looses its electrons. In this oxidation state increases.
  • Reduction reaction : It is the reaction in which a substance gains electrons. In this oxidation state decreases.

Half reactions of oxidation and reduction are :

Oxidation :2Cr\rightarrow 2Cr^(3+)+6e^-

Reduction :3Pb^(2+)+6e^-\rightarrow 3Pb

From the reduction reaction, we conclude that 6 moles of electrons gained by the 3 moles of lead ions.

Hence, the correct option is, (4) 6.0 mole

answer:  6......................
