Compound with amphoteric structure can act both as acid and base.
Therefore, the set -1 is Al2O3.xH2O(s), that forms Al(OH)4− in the solutions.
The set-3 is of acidic nature Al2O3.xH2O(s) that shows Al3+ and H2O .
Therefore, the set -1 is Al2O3.xH2O(s), that forms Al(OH)4− in the solutions.
The set-3 is of acidic nature Al2O3.xH2O(s) that shows Al3+ and H2O .

Amphoteric Nature of Al2O3.xH2O
Al2O3.xH2O(s) is an amphoteric substance, which means it can act as both an acid and a base. When it reacts with an acid, it acts as a base, and when it reacts with a base, it acts as an acid. The best sets of reactants that exhibit the amphoteric character of Al2O3.xH2O are:
Set-1: Al2O3.xH2O(s) and OH-(aq)
Set-2: Al2O3.xH2O(s) and H2O(l)
Set-3: Al2O3.xH2O(s) and H+(aq)
Set-4: Al2O3.xH2O(s) and NH3(aq)
Explanation:
Set-1: Al2O3.xH2O(s) and OH-(aq)
When Al2O3.xH2O(s) reacts with OH-(aq), it acts as an acid and donates a proton to form H2O(l) and Al(OH)4-(aq). Therefore, this set exhibits the amphoteric character of Al2O3.xH2O.
Set-2: Al2O3.xH2O(s) and H2O(l)
When Al2O3.xH2O(s) is added to water, it forms a weakly acidic solution due to the presence of hydrolyzed Al3+ ions. Therefore, this set also exhibits the amphoteric character of Al2O3.xH2O.
Set-3: Al2O3.xH2O(s) and H+(aq)
When Al2O3.xH2O(s) reacts with H+(aq), it acts as a base and accepts a proton to form H2O(l) and Al3+(aq). Therefore, this set does not exhibit the amphoteric character of Al2O3.xH2O.
Set-4: Al2O3.xH2O(s) and NH3(aq)
When Al2O3.xH2O(s) reacts with NH3(aq), it acts as an acid and donates a proton to form NH4+(aq) and Al(OH)3(s). Therefore, this set does not exhibit the amphoteric character of Al2O3.xH2O.
Conclusion:
From the above analysis, we can conclude that the best sets of reactants that exhibit the amphoteric character of Al2O3.xH2O are Set-1: Al2O3.xH2O(s) and OH-(aq) and Set-2: Al2O3.xH2O(s) and H2O(l).

Set-3: Al2O3.xH2O(s) and H+(aq)
Set-4: Al2O3.xH2O(s) and NH3(aq)
Explanation:
Set-1: Al2O3.xH2O(s) and OH-(aq)
When Al2O3.xH2O(s) reacts with OH-(aq), it acts as an acid and donates a proton to form H2O(l) and Al(OH)4-(aq). Therefore, this set exhibits the amphoteric character of Al2O3.xH2O.
Set-2: Al2O3.xH2O(s) and H2O(l)
When Al2O3.xH2O(s) is added to water, it forms a weakly acidic solution due to the presence of hydrolyzed Al3+ ions. Therefore, this set also exhibits the amphoteric character of Al2O3.xH2O.
Set-3: Al2O3.xH2O(s) and H+(aq)
When Al2O3.xH2O(s) reacts with H+(aq), it acts as a base and accepts a proton to form H2O(l) and Al3+(aq). Therefore, this set does not exhibit the amphoteric character of Al2O3.xH2O.
Set-4: Al2O3.xH2O(s) and NH3(aq)
When Al2O3.xH2O(s) reacts with NH3(aq), it acts as an acid and donates a proton to form NH4+(aq) and Al(OH)3(s). Therefore, this set does not exhibit the amphoteric character of Al2O3.xH2O.
Conclusion:
From the above analysis, we can conclude that the best sets of reactants that exhibit the amphoteric character of Al2O3.xH2O are Set-1: Al2O3.xH2O(s) and OH-(aq) and Set-2: Al2O3.xH2O(s) and H2O(l).
