Question

1.4 g of iron displaces 1.6 g of copper from a solution of copper sulphate. If the equivalent weight of the iron is 28, the equivalent weight of the copper will be:
(1) 16
(2) 32
(3) 48
(4) 64
​

Answer 1

equalient weight of copper is 48

Answer 2

Answer:

32

Explanation:

Given data:

1.4 g iron displaces 1.6 g of copper

i.e

Mass of iron = 1.4 g

Mass of copper = 1.6 g

Equivalent mass of iron = 28

therefore,

(Mass of Cu)/(Equivalent weight of Cu)=(Mass of Fe)/(Equivalent weight of Fe)

on substituting the values, we get

1.6/Equivalent weight of Cu = 1.4/28

or

1.6/Equivalent weight of Cu = 0.05

or

Equivalent weight of Cu = 1.6/0.05 = 32

Hence,

the correct answer is option (2) 32
