Introduction

Does An Electrolyte Behave

Like A Resistor?

Aim

To see the relationship between the Current and the Voltage for a liquid.

Circuit Diagram

Anode                          Cathode

Copper Sulphate (CuSO  ) solution

Method

This experiment was done as a demonstration. The results were obtained by adjusting the variable resistor to give a range of readings from the ammeter and voltmeter. These

Conclusion

        We could of collected more evidence towards the resistance of a liquid by doing more background work and further work. Some further work would have been trying to find out the outcome of the tests if we increased the voltage going into the circuit. We could have tried different solutions, e.g. Salt Water. We could also have tried the solution at different strengths, weak or strong, e.g. 0.5M.

  1. How does the mass of copper plated in the electrolysis of copper sulphate solution ...

    An advantage of using these values is that the highest value is 1 amp and this really should really give off that much energy into heat which would warm the copper sulphate solution. So this would help a lot in keeping the same temperature in the experiments.

  2. To find which of the circuits, shown below, are most suitable to measure a ...

    You can see this more clearly if you look in the percentage change column, for 50?, the total resistance calculated by the meter readings is 80% off the original resistance value. But as the resistances get higher for example 40000?, the total resistance calculated by the meter readings is only 0.1% off the original resistance value.

  1. Electrolysis of Copper Sulphate Solution.

    my prediction was correct as the concentration went down so did the current. I was also correct in that they are directionally proportional: Copper sulphate(ml) Current(amps) 100 0.13 50 0.54 It is roughly half of 13. My graph shows me that it is mostly a smooth curve accept for one anomalous result.

  2. The electrolysis of copper from copper sulphate solution

    The purification process begins is at the anode. I predict this because I think that this is where the copper will be deposited, the reason being, electrons are flowing from negative to positive. These electrons get rid of the coppers positive charge, leaving pure copper. The cathode has a thin sheet of pure copper roughly 99 percent pure.

    As the plates were 2cm wide and 6cm apart, this gave a volume of 12cm3 of the copper sulphate solution between the plates. The readings were taken and recorded. * More copper sulphate solution was added so that another centimetre of the plates was covered.
