Chapter 1 THE PROBLEM AND ITS BACKGROUND Introduction: People are using more and more household batteries. The average person owns about two button batteries‚ ten normal (A‚ AA‚ AAA‚ C‚ D‚ 9V‚ etc.) batteries‚ and throws out about eight household batteries per year. A battery is an electrochemical device with the ability to convert chemical energy to electrical energy to provide power to electronic devices. Batteries contain heavy metals such as mercury‚ lead‚ cadmium‚ and nickel‚ which can contaminate

application of the stoichiometric ratio between the electron and the gases‚ the fundamental electronic charge will be determined. THEORY H+ ions will join together at the cathode (the negative electrode) to produce H Atoms‚ and the H atoms will join to form molecules of H2 gas. At the positive electrode (the anode)‚ H20 molecules will decompose to replace the H+ ions lost and release O2 gas. The reactions appear below. 2H+(aq) + 2e- ---> H2(g) Reduction (at the cathode) 2H20(l) --->

However‚ the copper produced during the process is not pure enough for use‚ so it must be purified using electrolysis. During the process of purifying of the copper‚ the negative electrode‚ the cathode‚ which is the pure copper‚ and the positive electrode‚ the anode‚ which is the impure copper are both placed in a solution of copper sulfate. After a great amount of time‚ the electrical supply pulls electrons off of the copper atoms at the anode and the positive copper

Make a Battery from Potato Introduction: Batteries generate electricity through a chemical reaction between two different electrodes and one electrolyte. Use of Copper and Zinc electrodes and Sulfuric acid as electrolyte is a proven method for this process. We are wondering if we can use any other liquid as electrolyte? This gave us the idea of using a potato as electrolyte. After all a fresh potato has a lot of juice that may serve our purpose as electrolyte. Problem: Can Potato be used

two half cells connected internally by a salt bridge and externally by wires. A hydrogen half cell is the standard electrode and all comparisons of the other half cells are made against this half cell which has an E( value of zero volts. The E( values of other half cells are obtained by measuring the total emf (electromotive force/Eocell) when attached to a standard hydrogen electrode. All standard reduction potentials are measured with a solution concentration of 1 mol L-1‚ gas pressures of 101.3

electrolytic process requires an: 1. 2 Electrodes: An electrical conductor/terminal (usually metallic) through which electric current passes. They drive the electrolytic reaction by completing the circuit between the DC source and the electrolyte. An electrode In any electrochemical process is referred to either the Cathode and Anode Cathode: the electrode which becomes positively charged. During the process‚ negatively charged ions (Anions) move towards the electrode whilst positively charged ions (Cations)
