Electrochemical Cells

Year 11 Chemistry Electrochemical Cells Purpose To constringe down the order of reactivity for the coats copper, iron, lead and coat expend the to the lowest degree amount of electrochemical stalls as possible. Materials List Four one hundredml beakers 4 strips of dawn paper close together(p) 15cm in length Voltmeter Sodium Chloride tooth root at 10% concentration zinc, squealer, exceed and fight coat strips (approximately 10 cm) 50 ml of Copper sulfate, Zinc sulphate, Lead process and Iron process themes Scissors Procedure - bum the 50ml reply of zinc sulphate in a 100ml beaker, and 50ml solution of copper sulphate in a different 100ml beaker. prescribe the zinc metal strip in the zinc sulphate beaker and the copper metal strip with the copper sulphate beaker. - interpenetrate one of the leach paper strips in the sodium chloride solution, make received 100% of the surface has been cove red. Place one stop over of the filter paper in the zinc sulphate solution and the early(a) end in the copper sulphate solution (making sure the filter paper is not connecting the metals) - victimisation the voltmeter, touch both metals with the connecting wires so there is positive reading. criminal repose the voltage, anodic metal and cathodic metal. - Repeat this process using an Iron metal strip in 50ml of Iron nitrate solution and a lead metal strip in 50ml of lead nitrate solution. - Combine the most reactive (anodic) metals from the foremost two cellphones, to create the next cell. This combination will look into the overall 1st and 2nd most reactive.

The next cell set up will be the two least reactive (cathodic) metals from the first two cells, this will determine the third most reactive and the least reactive overall.
