When AgCl is dissolved in excess of each of N H 3 , KCN and N a 2 S 2 O 3 separately, the complex ions produced in each case are respectively

Options

  1. AAg N H 3 4 2 + , Ag CN 2 3 - , and A g 2 S 2 O 3 2 2 -
  2. BAg N H 3 2 + , Ag CN 2 - , and Ag S 2 O 3 2 3 -
  3. CAg N H 3 2 + , Ag CN 2 3 - , and A g 2 S 2 O 3 2 2 -
  4. DAg N H 3 2 2 + , Ag CN 2 3 - and A g 2 S 2 O 3 2 2 -

Correct answer

B. Ag N H 3 2 + , Ag CN 2 - , and Ag S 2 O 3 2 3 -

Step-by-step solution

When AgCl is dissolved in excess of each of N H 3 , KCN and N a 2 S 2 O 3 separately, the complex ions produced in each case are Ag N H 3 2 + , Ag CN 2 - , and Ag S 2 O 3 2 3 - respectively as follows AgCl + 2N H 4 OH → Ag N H 3 2 Cl + 2 H 2 O AgCl + 2KCN → K Ag CN 2 + KCl
