    current through a solution or molten salt (the electrolyte), resulting in the migration of ions to the electrodes: positive ions (cations) to the negative electrode (cathode) and negative ions (anions) to the positive electrode (anode). During electrolysis, the ions react with the electrode, either receiving or giving up electrons. The resultant atoms may be liberated as a gas, or deposited as a solid on the electrode, in amounts that are proportional to the amount of current passed, as discovered

    Electrolysis is a chemical reaction caused by electricity in solutions. Electrolysis can separate molecules (like separating water into hydrogen and oxygen gas, which is called electrolysis of water), electroplate a metal, can be used for welding, and can even be used for hair removal. Electrolysis was discovered by Alessandro Volta. The materials to cause electrolysis are a source of direct current (like batteries), electrolyte, and two electrodes. A direct current is current, which electricity

    Electrolysis is a process by which electrical energy is used to produce a chemical change. Maybe the most recognizable case of electrolysis is the deterioration of water into hydrogen and oxygen by methods for an electric ebb and flow. Electrolysis is important because it is used for making fertilizers, being made to be able to fuel cars. Right now it is used to fuel rockets but soon our cars will be able to use it as everyday fuel and extracting metals. In the study of electrolysis education.com

    Electrolysis How is the amount of copper deposited affected by the voltage? Aim The aim of this experiment is to find out what effect the change in voltage has upon the amount of copper deposited in 5 minutes. The voltages I will be using are 2, 4, 6, 8, 10 and 12volts; I will use these voltages because they are the only ones available on the power pack. I am doing the experiment for 5 minutes because it is enough time to get a result and it is short enough for doing 6 voltages in

    What is Electrolysis? Electrolysis is a chemical change brought about by the passing of an electric current through a solution or melt. It is also used to produce alkalis and elements such as chlorine and hydrogen. The process involves the addition (oxidation) or subtraction (reduction) of ions in elements. The electric current motions the ions to proceed onto the electrodes. For example, the cations (positive ions) move to the negative electrode (cathode) and the positive electrode (anode) will

    Electrolysis Aim: The aim of the investigation is to find the amount of copper gained or lost on the electrodes using a different amounts of current each time during electrolysis. How does the changing of the current and surrounding temperature effect the electrodes? Variables: Throughout the experiment I will change the amount of current used. I will measure the weight of the electrodes after each test. To make the test fair I will be keeping the same electrodes throughout the experiment

    Electrolysis Investigation Planning In this investigation, I will assess how changing the electric current in the electrolysis of acidified water affects the rate at which hydrogen gas is produced. The solution to be electrolysed is made up using acid and water. It is of little consequence what acid is used however in this case I will use Sulphuric acid (H2SO4). When H2SO4 is put in water it is dissociated and forms ions: H2SO4 → 2H (2+) + SO4 (2-) Ions are also present from

    Electrolysis Investigation Aim To investigate how voltage affects the amount of a copper (Cu) deposited during electrolysis of copper sulphate solution (CuSO4). Variables ========= TEMPERATURE - Approximately 20° centigrade.The higher the temperature, the faster the ions move through the solution. Thus, more copper is deposited in the given time period. ELECTROLYTE (CONCENTRATION) - 100g per litre. The denser the solution, the slower the reaction. The slower the reaction

    Investigating Electrolysis INTRODUCTION: In this experiment I will be investigating how the amount of copper affects the mass of the cathode. I will do this experiment twice so that I have an average of my results so that they are accurate. I have already done my preliminary work and from it, I have noticed that I will have to make some changes with the method of my experiment. AIM: In this experiment, I intend to find out how much copper in the solution affects the mass of the cathode
