Answer 1

The number of ligands in the complex compound formed when nitrate ion is poured in the solution of ferrous sulphate and sulphuric acid for the confirmation of nitrate ion is 1 as ;

Nitrates give brown fumes with concentrated H₂SO₄due to formation of NO₂. This is intensified upon adding copper turnings. Nitrate ion is confirmed by adding an aqueous solution of the salt to FeSO₄and pouring concentrated H₂SO₄slowly along the sides of the test tube, which produces a brown ring around the walls of the tube, at the junction of the two liquids caused by the formation of$Fe(NO{)}^{2+}$
