Answer» Consider the reactions: (a) $H_{3} P O_{2} (a q) + 4 A g N O_{3} (a q) + 2 H_{2} O (l) \to H_{3} P O_{4} (a q) + 4 A g (s) + 4 H N O_{3} (a q)$ (b) $H_{3} P O_{2} (a q) + 2 C u S O_{4} (a q) + 2 H_{2} O (l) \to H_{3} P O_{4} (a q) + 2 C u (s) + H_{2} S O_{4} (a q)$ (c) $C_{6} H_{5} C H O (l) + 2 [A g (N H_{3}) 2]^{+} (a q) + 3 O H^{-} (a q) \to C_{6} H_{5} C O O^{-} (a q) + 2 A g (s) + 4 N H_{3} (a q) + 2 H_{2} O (l)$ (d) $C_{6} H_{5} C H O (l) + 2 C u^{2 +} (a q) + 5 O H^{-} (a q) \to$ No change observed. What inference do you draw about the behaviour of $A g^{+} a n d C u^{2 +}$ from these reactions?
