Question
The solution of sodium meta aluminate on diluting with water and then boiling with ammonium chloride gives:
Options
A.[Al(H2O)5OH]2+
B.AlCl3
C.Al (OH)3
D.NaAl(OH)4
Solution
[Al(OH)4]- + NH4+ 
Al(OH)3 ↓ + NH3↑ + H2O
Hydroxide ion concentration is reduced owing to the formation of ammonia (a weak base) which escapes on boiling.
Al(OH)3 ↓ + NH3↑ + H2OHydroxide ion concentration is reduced owing to the formation of ammonia (a weak base) which escapes on boiling.
