# Investigation on the conductive properties of copper sulphate solution.

Extracts from this document...

Introduction

Jonathan Man

Investigation on the conductive properties of copper sulphate solution.

## Aim

I hope to measure the conductivity of copper sulphate solution. I will use a method similar to electrolysis to achieve this. The only difference will be that I am using an alternating current rather than a direct current so that copper from the copper sulphate solution will not be electrolysed.

I chose this topic because I wanted to find out if the conductivity of copper sulphate solution changes with different cross-sectional areas.

Equipment:

Plastic container measuring L=0.13m, W=0.05m, H=0.06m

Copper electrodes X2

Wires

Crocodile clips

AC power supply

1. ## The aim of my investigation is to determine the specific heat capacity of aluminium.

a body is proportional to the difference in temperature between the body and its surroundings, i.e. (Rate of loss of heat to surroundings) ? (Excess temperature) Or (Rate of loss of heat to surroundings) = k (?-?o) This applies when a body is cooling under conditions of forced convection.

2. ## Magnetism Investigation

If the beam is jarred inadvertently, make sure you break the circuit before attempting to set it back into place. You may use the beam lift to reposition the beam. If you must do this, be sure to check the equilibrium reading on the telescope with the current turned off, making sure it agrees with the previous equilibrium value.

2. ## Investigate the properties of a sensor.

Below is a circuit diagram for our experiment. We conducted preliminary tests to find out if there were any factors we might have overlooked and also to get an idea of the type of results we would be dealing with. Firstly we had to see which scale was right for the size of measurements we were taking.

I will also take 2 readings for each measurement by breaking the circuit and reconnecting it. All my current readings will be taken in mA, as this will enable patterns to be seen in my results and on graphs. The current will gradually become weaker as the graphite paper gets longer.
