Card preview (23)

#1
Front (Question)

Reactions of copper (II), iron (II), iron (III) and aluminium (III) aqua ions with Sodium Hydroxide Exception and explain

Back (Answer)

All four metal aqua ions will form precipitates with NaOH. Only the aluminium hydroxide precipitate will dissolve in an excess of NaOH as it’s amphoteric

#2
Front (Question)

Reactions of copper (II), iron (II), iron (III) and aluminium (III) aqua ions with Ammonia Exception and explain

Back (Answer)

All four metal aqua ions will form precipitates with ammonia. Only the copper hydroxide precipitate will dissolve in an excess of ammonia. This is because it undergoes a ligand exchange reaction with excess ammonia

#3
Front (Question)

Reactions of copper (II), iron (II), iron (III) and aluminium (III) aqua ions with Sodium Carbonate Solutions containing Al3+ or Fe3+

Back (Answer)

All four metal aqua ions will form precipitates with sodium carbonate. Also form bubbles as CO2 is formed
