The equivalent weight of copper is4 g of copper was dissolved in concentrated nitric aci(d) The copper nitrate solution on strong heating gave 5 g of its4 g of copper was dissolved in concentrated nitric aci(d) The copper nitrate solution on strong heating gave 5 g of its

Options

  1. A12
  2. B20
  3. C23
  4. D32

Correct answer

D. 32

Step-by-step solution

Copper on reacting with conc. HNO 3{ }_{3} gives copper nitrate.
4 g of copper was dissolved in concentrated nitric aci(d) The copper nitrate solution on strong heating gave 5 g of its
On strongly heating with copper nitrate, copper oxide is obtained.
4 g of copper was dissolved in concentrated nitric aci(d) The copper nitrate solution on strong heating gave 5 g of its
∴\therefore Equivalent weight of Cu=\mathrm{Cu}= Weight of copper ×\times Equivalent weight of oxygen =4×8=32=4 \times 8=32
