An Investigation into Electrolysis - Copper Sulphate

- 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 substance stays in the solution whereas the less reactive is released and appears as a gas (hydrogen) or a coating of metal....   [tags: Papers]

Copper Mining

- Copper Mining Copper mining has become a very important industry in today’s society. It is also one of man’s oldest commercial activities. There are many steps from finding a mine site to producing a product made of copper or a copper alloy. The mining industry has also had many important developments from the time the first mine was formed in Rio Tinto in 3000 B.C. The earliest copper sources were globules and chunks of native copper found on the Earth’s surface. After we quickly exhausted the limited amount of native copper, we were forced to look underground for more sources....   [tags: Natural Resources Minerals Miners Essays]
