An acidic solution of 'X' does not give precipitate on passing H2S through it. 'X' gives white precipitate when NH4OH is added to it. The white precipitate dissolves in excess of NaOH solution.Pure 'X' fumes in air and dense white fumes are obtained when a glass rod dipped in NH4OH is put in the fumes. Compound 'X' can be [1999]

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.
