The Best Possible Temperature For Electrolysis Essay

, Research Paper

Aim: ??????????? .Factors to be affected: ??????????? TemperatureFactors not to be affected: ??????????? Concentration,

Current, Surface Area, Air Pressure And Weight Of Brass And Copper Plates.Hypothesis: ??????????? I

hypothesise that as the temperature increases the electrolysis will take place

faster and more efficiently because particles move faster when there is more

heat. This is because of the kinetic theory, the more heat, the more energy so

the particles move faster.Apparatus: ??????????? 1 battery

pack, 1 ammeter, 1 variable resistor, 1 set of electronic scales, 1 200ml

beaker, 2 crocodile clips, wire and 1 piece of cardboard.Consumables ??????????? 200ml

copper (II) sulphate solution, 6 copper plates and 6 brass platesMethod: ??????????? Weigh a

copper plate and a brass plate. Record these on your results table. Attach them

to a piece of cardboard, attach a crocodile clip to each metal plate connecting

to the circuit (shown; fig 1). The power from the battery pack should be set at

0.2A. Place the piece of cardboard on top of a beaker filled with 200ml copper

(II) sulphate solution. Place this in a water bath set to the desired

temperature. Then turn the current on for 10 minutes. After the 10 minutes

weigh both plates again. Record these on your table of results.Safety: ??????????? Do not

eat or drink any of the materials involved in this process, wear eye protection

at all times and do not electricute yourself or anybody near you
