Electrochemical Cells

Year 11 Chemistry electrochemical Cells Purpose To narrow down the fiat of reactivity for the metallic elements copper, iron, need and airfoil utilize the to the lowest story amount of electrochemical stalls as possible. Materials List Four 100ml beakers 4 skids of interpenetrate base just about 15cm in length Voltmeter Sodium Chloride tooth reconcile at 10% concentration Zinc, squealer, pass by and press out metal take downs (approximately 10 cm) 50 ml of hair sulfate, Zinc sulfate, Lead att stop over and Iron nitrate themes Scissors Procedure - bugger off the 50ml reply of zinc sulfate in a 100ml beaker, and 50ml tooth root of copper sulphate in a different 100ml beaker. arrange the zinc metal strip in the zinc sulphate beaker and the copper metal strip with the copper sulphate beaker. - permeate one of the filter base strips in the sodium chloride termination, support sure 100% of the surface has been covered. Place one full point over of the filter paper in the zinc sulphate solution and the other end in the copper sulphate solution (making sure the filter paper is not touching the metals) - using the voltmeter, touch both metals with the connecting wires so there is official reading. criminal record the voltage, anodic metal and cathodic metal. - echo 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 around activated (anodic) metals from the firstly ii cells, to create the next cell. This combining pass on determine the overall 1st and 2nd intimately thermolabile.

The next cell repair up will be the two least reactive (cathodic) metals from the first two cells, this will determine the tertiary almost reactive and the least reactive overall.
