Question

1)2.08g of zinc displaced 6.9119g of silver from a solution of silver nitrate. If the equivalent weight of
silver is 108, then the equivalent weight of zinc is
a) 65.00
b) 32.5
c) 64.50
d) 31.50​

Answer 1

Answer:

As per your question given,the chemical reaction is as follows:

3Zn+2AgNo3 gives rise to 3ZnO2+2Ag

Oxidation state of Ag in reactant side = 2*1=2

Oxidation state of Ag in product side= 2*0=0

Equivalent Weight of Ag=Gram molecular weight / change in valency

=108/2

=54gms

Equivalent weight of Ag=54gms
