Question. A hydrated salt (A) of a divalent metal shows the following: (i) Violet color in borax bead test in both oxidizing and reducing flames. (ii) White precipitate with BaCl₂ solution that is insoluble in concentrated HCl. (iii) On strong heating, it decomposes to give a residue (B) and gaseous oxides of sulfur. (iv) 2.77 g of (A) on complete thermal decomposition gives 0.71 g of residue (B). Identify salt (A) and find the number of water molecules of crystallization.
Answer: Salt (A) is MnSO₄·7H₂O (manganese sulfate heptahydrate) with 7 water molecules of crystallization
This example was solved twice independently and both solutions agree.
