4 g of copper was dissolved in concentrated nitric acid. The copper nitrate solutio on strong heating gave 5g of its oxide. The equivalent weight of copper is

A

23

B

32

C

12

D

20

Text Solution

Verified by Experts

The correct Answer is:
b
`because4g` of copper gave 5g of its oxide means , 1 g of oxygen cpmbine with 4g of copper .
`because` Eq . Wt of oxygen =8,
Therefore ,
8g of oxygen combine with `=4xx8` g of copper =32 g
Hence ,
Equivalent weight of copper =32
