An Investigation into Electrolysis - Copper Sulphate Introduction Decomposition caused by electricity is called electrolysis. The electrical energy causes a chemical change. When a salt is dissolved in water, its ions become free to move so the solution can be "electrolyzed." The products of the electrolysis depend on the chemical solution, its strength and the type of electrode. The cathode is negatively charged and therefore attracts to it positive ions. E.g. hydrogen. The more reactive

Electrolysis of Copper in Copper Sulphate Solution Introduction Aim This is an investigation into how temperature affects the amount of copper lost from the Anode and gained on the Cathode during electrolysis. Electrolysis is… The chemical change by passing electric charge through certain conducting liquids (electrolytes). The current is conducted by migration of ions - negative ones from the Anode (positive electrode), and positive ones to the Cathode (negative electrode).

The Factors that Affect the Mass of Copper Background Information ====================== Electrolysis is the decomposition of a molten or aqueous compound by electricity. Electrolysis occurs only in liquids called electrolytes. Electrolytes are compounds, which conduct electricity when molten or dissolved in water, but not when they are in a solid state as the oppositely charged ions are held together by strong ionic bonds in a giant lattice and this means electricity cannot pass through
Copper Collected At The Cathode Aim: The aim of this investigation is to find out how current affects the amount of copper formed at the cathode, when using copper sulphate solution and graphite electrodes.

experiment is carried out for. The greater the time the electrodes are left in the solution, the more time there is for the copper to be gathered at the anode. The third variable that affects the experiment is the temperature of the copper II sulphate solution. As the temperature of the solution increases, more of the ions gain kinetic energy and begin to move faster. This enables the positive and negative charged ions to collide faster with the electrodes. As more of the positive and negative
Egg Albumen Experiment The purpose of this investigation is to establish which is the lowest concentration of Copper (II) Sulphate solution that will denature a sample of egg albumen (egg white) at room temperature. The base of the reaction is the globular protein (albumen) being denatured by a heavy metal (Copper (II)), the copper (II) reacts with the NH3 group causing it to denature, this means the proteins' secondary and tertiary structures are being altered and refolding into different
