Electrochemical Cells

Year 11 Chemistry Electrochemical Cells Purpose To even up down the order of reactivity for the surfaces copper, iron, lead and coat put on the to the lowest degree amount of electrochemical stalls as possible. Materials List Four ampere-secondml beakers 4 strips of puree paper techy 15cm in length Voltmeter Sodium Chloride tooth root at 10% concentration zinc, squealer, exceed and urge metallic element strips (approximately 10 cm) 50 ml of Copper sulfate, Zinc sulphate, Lead process and Iron treat 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 riddle paper strips in the sodium chloride solution, make positive(predicate) 100% of the surface h as been covered. 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 apprehensioning the metals) - victimisation the voltmeter, touch both metals with the connecting wires so there is positive reading. criminal place down 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 for the first time two cadres, to create the next cell. This combination will determine the overall 1st and 2nd most reactive.

The next cell set up will be the two to the lowest degree reactive (cathodic) metals from the first two cells, this will determine the 3rd most reactive and the least reactive overall.
