Question

Q. Distinguish between the following pairs of compounds using the test given within brackets:
Iron (II) sulphate and iron (III) sulphate (using ammonium hydroxide)

Answer 1

Lead salt gives chalky with precipitates of lead hydroxide with ammonium hydroxide. This precipitates are insoluble in excess.Zinc salt gives gelatinous with precipitates of zinc hydroxide with ammonium hydroxide. This precipitates are soluble in excess.

Answer 2

Lead salt gives chalky with precipitates of lead hydroxide with ammonium hydroxide. This precipitates are insoluble in excess.Zinc salt gives gelatinous with precipitates of zinc hydroxide with ammonium hydroxide. This precipitates are soluble in excess.
