Answer»

Consider
the reactions:

(a)
H₃PO₂(aq)
+ 4 AgNO₃(aq)
+ 2 H₂O(l)
→ H₃PO₄(aq)
+ 4Ag(s) + 4HNO₃(aq)

(b)
H₃PO₂(aq)
+ 2CuSO₄(aq)
+ 2 H₂O(l)
→ H₃PO₄(aq)
+ 2Cu(s) + H₂SO₄(aq)

(d)
C₆H₅CHO(l)
+ 2Cu²⁺⁽aq)
+ 5OH^–(aq)
→ No
change observed.

What
inference do you draw about the behaviour of Ag⁺
and Cu²⁺
from these reactions?
