Aluminium and Titanium 0.0 / 5 ? ChemistryMetals, metal ores and alloysGCSEAQA Created by: Megan xCreated on: 07-06-14 13:59 Why are Aluminium and Titanium useful? They have low densities and are resistant to corrosion. 1 of 10 Describe what happens when aluminium reacts with oxygen. Aluminium reacts with the oxygen in the air and creates a layer of aluminium oxide that coats the metal. 2 of 10 What does this aluminium oxide layer prevent? Prevents further corrosion. 3 of 10 What is Aluminium commonly used for? Drink cans, aeroplanes, window frames. 4 of 10 What is Titanium used for? Aeroplanes, replacement hip joints, nuclear reactors. 5 of 10 Is Aluminum and Titanium more reactive than carbon or less reactive? More reactive than carbon. 6 of 10 What method is used to extract Aluminum form its ore called? Electrolysis. 7 of 10 Why is Aluminum expensive? Because it is extracted by the process of electrolysis, which is expensive. 8 of 10 Why is Electroysis expensive? Because it's complex, has many different stages, requires a large amount of energy, which makes it very expensive. 9 of 10 Why should we recycle materials wherever possible? To save money and energy. To make sure that we do not use all of the natural resources. To reduce the amount of mining which damages the environment. 10 of 10
