Yanik Chauvin Electrolysis is a process by which electrical energy is used to produce a chemical change. Perhaps the most familiar example of electrolysis is the decomposition breakdown of water into hydrogen and oxygen by means of an electric current. The same process can be used to decompose compounds other than water.

Chemistry seems challenging to most students because there are a great deal of % Money Back Guarantee · hour customer service. As we have covered, electrolysis is the passage of a direct electric current through an ionic substance that is either molten or dissolved in a suitable solvent. This results in chemical reactions at the electrodes and the separation of materials. Two commonly used methods of electrolysis involve molten sodium chloride and aqueous sodium chloride. Electrolysis Using Copper Sulphate And Copper Electrodes Introduction In this experiment copper sulphate will be electrolysed using copper electrodes to find the loss of mass of the anode. The copper anode will be weighed before and after the experiment. Candidate Number Chemistry Coursework read more. The above preview is.

The board exams for vocational subjects will take place first and core subjects exam will be held afterwards.|ˈkeməstrē|: the branch of science that deals with the identification of the substances of which matter is composed; the investigation of their properties and the ways in which they interact, combine, and change; and the use of these processes to form new substances.
Chemistry is an amazing subject. It's probably the hardest science to grasp for most people, but I love this science. Chemistry is the study of the composition, behaviour and properties of matter, and of the elements of the Earth and its atmosphere.
