Consider the reactions :
(a)H 3 P O 2 ( a q ) + 4 A g N O 3 ( a q ) + 2 H 2 O ( l ) H 3 P O 4 ( a q ) + 4 A g ( s ) + 4 H N O 3 ( a q )
(b)H 3 P O 2 ( a q ) + 2 C u S O 4 ( a q ) + 2 H 2 O ( l ) H 3 P O 4 ( a q ) + 2 C u ( s ) + H 2 S O 4 ( a q )
(c)C 6 H 5 C H O ( l ) + 2 [ A g ( N H 3 ) 2 ] ( a q ) + + 3 O H ( a q ) – C 6 H 5 C O O ( a q ) – + 2 A g ( s ) + 4 N H 3 ( a q ) + 2 H 2 O ( l )
(d)C 6 H 5 C H O ( l ) + 2 C u ( a q ) 2 + + 5 O H ( a q ) –
What inference do you draw about the behaviour ofA g + C u 2 +
(a)
(b)
(c)
(d)
What inference do you draw about the behaviour of
Solution:
Reactions (a) and (b) indicate that both A g N O 3 C u S O 4 H 3 P O 2 H 3 P O 4
Reactions (c) and (d) suggest that[ A g ( N H 3 ) 2 ] + C 6 H 5 C H O C 6 H 5 C O O – C u 2 + C 6 H 5 C H O C 6 H 5 C O O – A g + C u 2 +
Reactions (c) and (d) suggest that
