(C) Cyanide ion is used as ligand for leaching of silver.
(D) Phosphine act as a ligand in Wilkinson catalyst.
(E) The stability constants of Ca^(2+) and Mg^(2+) are similar with EDTA complexes.
Choose the correct answer from the options given below:

Select the correct option:

(B), (C), (E) only

(C), (D), (E) only

(A), (B), (C) only

(A), (D), (E) only

✓ Correct! Well done.

✗ Incorrect. Try again or view the solution.

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
