A) A precipitate is formed which does not dissolve in excess of ammonium hydroxide
B) A precipitate is formed which dissolves in excess of ammonia solution
C) No precipitate is formed
D) None of these
Correct Answer: A
Solution :
[a] \[A{{l}_{2}}{{\left( S{{O}_{4}} \right)}_{3}}+6N{{H}_{4}}OH\xrightarrow{{}}\] \[2Al{{\left( OH \right)}_{3}}+3{{\left( N{{H}_{4}} \right)}_{2}}S{{O}_{4}}\] \[Al{{\left( OH \right)}_{3}}+NaOH\xrightarrow{{}}\underset{Soluble\text{ }complex}{\mathop{N{{a}^{+}}{{\left[ Al{{\left( OH \right)}_{4}} \right]}^{-}}}}\,\] It is insoluble in \[N{{H}_{4}}OH.\]
