In quantitative analysis of second group in lab. \(H_2S\) gas is passed in acidic medium for ppt. When \(Cu^{+2}\) and \(Cd^{+2}\) react with \(KCN\), than in which of the following condition, ppt will not be formed due to relative stability:
In quantitative analysis of second group in lab. \(H_2S\) gas is passed in acidic medium for ppt. When \(Cu^{+2}\) and \(Cd^{+2}\) react with \(KCN\), than in which of the following condition, ppt will not be formed due to relative stability:
\(K_2[Cu(CN)_4] – More\ stable\)
\(K_2[Cd(CN)_4] – Less \ stable\)\(K_2[Cu(CN)_4] – Less \ stable\)
\(K_2[Cd(CN)_4] – More\ stable\)\(K_3[Cu(CN)_4] – More\ stable\)
\(K_2[Cd(CN)_4] – Less \ stable\)\(K_3[Cu(CN)_4] – Less\ stable\)
\(K_3[Cd(CN)_4] – More \ stable\)
The Correct Option is C
Solution and Explanation
\(K_3[Cu(CN)_4]\) is more stable than \(K_2[Cd(CN)_4]\), which means that the complex with \(Cu^{2+}\) is more stable and less likely to precipitate compared to the complex with \(Cd^{2+}\).
So, the correct option is (C): \(K_3[Cu(CN)_4] – More\ stable\), \(K_2[Cd(CN)_4] – Less \ stable\)

Concepts Used:
Coordination Compounds
A coordination compound holds a central metal atom or ion surrounded by various oppositely charged ions or neutral molecules. These molecules or ions are re-bonded to the metal atom or ion by a coordinate bond.
Coordination entity:
A coordination entity composes of a central metal atom or ion bonded to a fixed number of ions or molecules.
Ligands:
A molecule, ion, or group which is bonded to the metal atom or ion in a complex or coordination compound by a coordinate bond is commonly called a ligand. It may be either neutral, positively, or negatively charged.
