Consider the following statements `:` `S_(1) :` A metal chloride on heating with an aqueous solution of `K_(2)Cr_(2)O_(7)` and concentral `H_(2)SO_(4)` produces deep red vapours. `S_(2) :` Lead nitrate dissolved in water responds to brown ring test. `S_(3) :` Deep red solution of ferric acetate on boiling with water turns to brownishred solution. `S_(4) : NaNO_(2)` solution acidified with acetic acid produces blue colour with iodide solution and starch paste of these.
