GCSE PHYSICS COURSEWORK In this experiment we are investigating the effect of concentration on the current flowing through a copper sulpahte solution. Prediction I think that the higher the concentration the higher the current passing through the solution, I also think that the higher the voltage, the higher the current. I think this will happen because there will be more copper sulphate molecules. Since there are more copper sulphate molecules, then there will be more sulphate ions giving up electrons to the anode (positive electrode) and more copper ions receiving electrons from the cathode, this means that there will be more electrons being transferred and so a higher current. The ions will break their ionic bonds because the copper plates are given a larger positive and negative charge by the battery (the circuit) and so the small force holding the ions together will be overpowered by the larger force of the electrodes on...
