Q. A certain sample of cuprous sulphide is found to have the composition $Cu_{1 . 92}S_{1 . 00}$ because of incorporation of $Cu^{2 +}$ and $Cu^{+}$ ions in the crystal then ratio of $Cu^{2 +}$ and $Cu^{+}$ ions is:

Solution:

$Cu_{1 . 92}S_{1 . 00}$
Solution
on charge balancing $\left(x\right)+\left(192 - x\right)2=200\Rightarrow x=184$
$\frac{Cu^{+}}{Cu^{+ 2}}=\frac{x}{192 - x}=\frac{184}{8}=\frac{23}{1}$
