Q. 3. Copper metal was obtained in middle east from charcoal reduction of its ores. Copper is resistant to oxidation but over a long time the metal acquires a coating of green crust called Patina. Although trace amounts of copper are essential for all forms of life, but the metal is toxic in large amounts. Blue vitriol, CuSO4.5H2C, is used as pesticide and wood preservative. Blue vitriol is a complex compound. Answer the following questions : (i) What is the coordination number of blue vitriol complex? Give geometry of this complex also. (ii) How many water molecules is/are hydrogen bonded to sulphate ion? (iii) What is the chemical composition of Patina?
