Question

the preparation of a salt "X" which forms dirty green precipitate when NH4OH is added to its solution is given below. Take 'Y' in a beaker and add iron fillings. Heat slowly till effervescence ceases and no more Fe dissolves. Filter the contents of the beaker to remove residual iron fillings along any impurities. Evaporate the filtrate to the point of crystallization. Cool the hot saturated solution. The salt 'X' crystallizes out. Filter and dry the crystals.
1. Identify Y.
2. State molecular fomula of X.
3. State the method of preparation (type of reaction) of X.
4. The crystals of X are _____ (soluble/insoluble) in water.
5. Give examples of another salt that can be prepared by this method.​
