Electrolysis of Copper Sulphate Solution Introduction In wires, current is a flow of electrons, in liquids, the current is a flow of ions. The ions have a positive or negative charge and the electrons have a negative charge. Ions can move about if the substance is either dissolved or melted. Negatively charged ions move to the positive electrode and the positively charged move towards the negatively charged electrode. When this occurs, the substance has been split in to two substances, this is called electrolysis. Copper sulphate Solution is split in to copper ions, which are positively charged and go to the negative electrode and into Sulphate, which is negatively charged and goes to the positive electrode. Variables The variables I could investigate are: * The current The more current, the more copper will be deposited * The voltage The more voltage, the more copper will be produced * The concentration The higher the concentration, the more ions will be present * Volume...
