A) acidic
B) basic
C) amphoteric
D) none of these
Correct Answer: A
Solution :
\[AlC{{l}_{3}}+3{{H}_{2}}O\underset{Weak\,base}{\mathop{Al{{(OH)}_{3}}}}\,+\underset{Strong\,acid}{\mathop{3HCl}}\,\] Aqueous solution of \[AlC{{l}_{3}}\] is a solution of strong acid \[(HCl)\] and weak base \[(Al{{(OH)}_{3}})\]. Thus, the resultant solution will be acidic.
