Question

AgCl is dissolved in excess of each of N H 3 , KCN and N a 2 S 2 O 3 . The complex ions produced in each case are, [ A g ( N H 3 ) 2 ] 2 + , [ A g ( C N ) 2 ] 3 - and [ A g ( S 2 O 3 ) 2 ] 2 -, [ A g ( N H 3 ) 2 ] + , [ A g ( C N ) 2 ] 3 - , and [ A g ( S 2 O 3 ) 2 ] 2 -, [ A g ( N H 3 ) 2 ] + , [ A g ( C N ) 2 ] - , and [ A g ( S 2 O 3 ) 2 ] 3 -, [ A g ( N H 3 ) 4 ] 2 + , [ A g ( C N ) 2 ] 3 - , and [ A g 2 ( S 2 O 3 ) 2 ] 2 -

Here following reactions occur as follows A g C l + 2 N H 4 O H → [ A g ( N H 3 ) 2 ] C l + 2 H 2 O A g C l + 2 K C N → K [ A g ( C N ) 2 ] + K C l A g C l + N a 2 S 2 O 3 → N a 3 [ A g ( S 2 O 3 ) 2 ] S o d i u m a r g e n t o t h i o s u l p h a t e + N a C l
