a DISPLACEMENT OF COPPER FROM AQUEOUS SOLUTION OF COPPER IONS i A metal higher in the activity order can displace copper metal from a solution of copper ions Put 10 mL of molar copper sulphate solution in a small beaker Clean magnesium ribbon and cut into 05 cm pieces Add these pieces to the copper sulphate solution one at a time The reaction can be vigorous Copper metal deposits and the blue colour gradually disappear as the magnesium displaces the copper ion Note any heat given out by the reaction When the solution is colourless decant the solution from the red copper powder at the bottom of the beaker Collect the copper and dry it Mgs  Cu2aq  Mg2aq  Cus ii Repeat the experiment by attempting to displace copper metal using powdered zinc and iron metal Note the comparative activity of the metals
