4 g of copper was dissolved in concentrated nitric aci(d) The copper nitrate solution on strong heating gave 5 g of its oxide. The equivalent weight of copper is
Options
- A12
- B20
- C23
- D32
Correct answer
D. 32
Step-by-step solution
Copper on reacting with conc. HNO ₃ gives copper nitrate. On strongly heating with copper nitrate, copper oxide is obtained. Equivalent weight of Cu = Weight of copper Equivalent weight of oxygen =4 8=32
