Investigating the rate of electrolysis. An investigation to find out what factors affect the rate of electrolysis of a solution containing copper (II) ions. Plan It is known that by passing a constant electric current through a copper sulphate solution the passage of ions through this solution results in copper atoms being dissolved into the solution from the anode‚ which has a positive charge while positive copper‚ ions (cations) are also being discharged at the cathode which has a negative charge

Part Ca)Up until the 1940’s rubber had only been obtained from the latex of rubber trees(Hevea brasiliensis) in plantations situated in tropical areas such as Malaya and Burma. The demand for rubber increased significantly during world war 2 as rubber was needed for tyres of military vehicles and the supply was interrupted by the conflict between the countries. Scientists in Germany and the US developed synthetic polymers that could replace rubber. Even after the war ended the traditional sources

Chemistry Essay The Importance Of Electrolysis in Our Daily Lives “Electrolysis is the process by which ionic substances are decomposed (broken down) into simpler substances when an electric current is passed through them.” Electrolysis has a few main components like a battery‚ electrodes and electrolyte. In our daily lives we can see the applications of electrolysis in many ways. Some of the process of electrolysis is used for accumulators (car batteries)‚ electroplating‚ electrotyping‚ electrolytic

Analyzing electrolytes I. Introduction Ionic substances form when a metal reacts with a non-metal. They contain charged particles called ions. Those ionic substances are broken down by electrolysis. Electrolysis is the breakdown of a substance by electricity‚ and it only happens in liquids. The liquids that can be electrolyzed are called electrolytes. When said electrolyzed‚ means that the compounds in solutions are broken down when they conduct electricity. Its necessary the use of electrodes

properties. Reduction means removal of oxygen or gain of electrons. Carbon is a good chemical reducing agent because it readily combines with oxygen‚ but it is only useful for the metals below it in the Reactivity Series. In the process of electrolysis‚ the positive metal ions in the compound gain electrons to become atoms of the elements.

it is costly to produce and difficult to store. Two of the methods of producing hydrogen are by reforming natural gas‚ or electrolysis of water. Reforming natural gas is a method to produce hydrogen by exposing natural gas to high temperature steam‚ and convert carbon monoxide with steam to produce additional hydrogen and carbon dioxide. The production process of electrolysis is to use electric energy to split water into hydrogen and oxygen gas. Two of the methods to store hydrogen are compressed
