# Does An Electrolyte Behave Like A Resistor?

Extracts from this document...

Introduction

## 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

The graph is showing a straight line through the origin. This means that as the

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.

However, as the copper sulphate solution all came from the same container, it stayed very even throughout. * Safety goggles were worn to prevent any copper sulphate getting into eyes and lab coats were worn to prevent damage to clothes.

Also I can investigate what other affect a small current has on the copper sulphate solution e.g. the increase in temperature. Secondly I have a constant amount of current increasing which makes it easier to calculate the changes of between each different experiment and so when I draw the graph I can see how the mass changes.

I will also try to use the same batch of copper sulphate. I will also keep the total volume the same and the voltage setting, the distance between the electrodes. I will also keep the current and the depth of the electrode in the solution the same.
