MCQ Solution: Solutions
A certain sample of cuprous sulphide is found to have composition Cu1.8S, because of incorporation of Cu2+ ions in the lattice. What is the mole %of Cu2+ in total copper content in this crystal?
1) 99.8%
2) 11.11%
3) 88.88%
4) None
Solution
Let us consider the problem:
Two Cu+ replaced 1 Cu2+ in Cu2S sample.
Total loss of Cu=0.2mole
Since of Cu2+ in total copper content =0.21.8×100=11.11%
