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. The electrolysis of copper from copper sulphate solution

    cathode drop off and are left at the bottom of the beaker. Key Variables: Temperature - temperature may have an affect on the current. The reason is that if the temperature is higher, then the particles will move more quickly thus causing more collisions and producing more energy.

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

    I investigated further by conducting more calculations for circuit One, to find out at which value it would be the same as Circuit Two (40? off labelled resistance value): Circuit One Value specified on Resistor (?) Value Obtained due to calculations (?)

  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.

    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.

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

    I expect the current to be directly proportional to mass gained at cathode and lost at the anode. The Values For the time allowance I am going to use 10 min. I think that is enough time for electrons be turning copper ions from the anode into copper atoms and letting them cling onto copper at the cathode.
