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 results are shown in results table and the graph.

Conclusion

        The graph is showing a straight line through the origin. This means that as the voltage increases, the current also increases uniformly.

        A graph of Voltage and Current for a resistor was the same, when I did the experiment. This means that the liquid behaves like a resistor. Which was what we were trying to find out.

        In a liquid, a current is the movement of ions. In Copper Sulphate (CuSO  ) solution the sulphate ions are negative and move to the anode, the copper ions are ...
