Solution
Based on Hall- Heroults process
$\left[\mathrm{Rh}\left(\mathrm{PPh}_3\right)_3 \mathrm{Cl}\right]$ Wilkinson's catalyst
$$
\mathrm{Ag}_2 \mathrm{~S}+\mathrm{NaCN} \stackrel{\text { Air }}{\rightleftharpoons} \mathrm{Na}\left[\mathrm{Ag}(\mathrm{CN})_2\right]+\mathrm{Na}_2 \mathrm{~S}
$$
$\mathrm{Ca}^{++}$ion forms more stable complex with EDTA
