Identification of Compound X
Acidic Solution of X Does Not Give Precipitate on Passing H2S Through It
This indicates that there is no presence of sulfide ions in the compound X.
X Gives White Precipitate When NH4OH is Added to It
This indicates that the compound X is a metal cation that forms a white precipitate with hydroxide ions.
The White Precipitate Dissolves in Excess of NaOH Solution
This indicates that the white precipitate formed is an amphoteric hydroxide that dissolves in excess of a strong base due to the formation of a soluble complex.
Pure X Fumes in Air
This indicates that the compound X is volatile and can evaporate easily.
Dense White Fumes are Obtained When a Glass Rod Dipped in NH4OH is Put in the Fumes
This indicates that the compound X reacts with NH4OH to form a volatile compound that fumes in air.
Compound X Can Be ZnCl2, FeCl3, AlCl3, or SnCl2
ZnCl2 is the correct answer because it fits all the observations made. Zinc is a metal cation that forms a white precipitate with NH4OH, and the precipitate dissolves in excess NaOH to form a soluble complex. Zinc is also volatile and can fume in air, and it reacts with NH4OH to form a volatile compound that fumes in air. FeCl3 and AlCl3 both give a brown precipitate with H2S, while SnCl2 gives a black precipitate with H2S. Therefore, they do not fit the observation that X does not give a precipitate with H2S.
