Chapter 19, Problem 89A
Interpretation Introduction

(a)

Interpretation:

Chemical equation is to be written. Oxidation states are to be determined. Half cell reactions are to be written. Then balancing is to be done.

Concept introduction:

Oxidation involves loss of electron which is represented by oxidation half reaction and reduction involves gain of electron which is represented by reduction half reaction.

Answer to Problem 89A

Cu+AgNO3Ag+Cu(NO3)2

Oxidation states:

Cu0+Ag+1N+5O23Ag0+Cu+2(N+5O23)2

Oxidation half equation:

CuCu2++2e

Reduction half reaction:

Ag++eAg

Balanced equation:

Cu+2Ag+2Ag+Cu2+

Or

Cu+2AgNO32Ag+Cu(NO3)2

Explanation of Solution

Cu+AgNO3Ag+Cu(NO3)2

Oxidation states:

Cu0+Ag+1N+5O23Ag0+Cu+2(N+5O23)2

Oxidation half equation:

CuCu2++2e

Reduction half reaction:

Ag++eAg

Adding both equations after multiplying reduction half cell with 2

Balanced equation:

Cu+2Ag+2Ag+Cu2+

Or

Cu+2AgNO32Ag+Cu(NO3)2
