Aluminium sulphate, often called alum, is used in paper making to increase the paper’s stiffness and smoothness and to help keep the ink from running. It is made from the reaction of sulfuric acid with the aluminium oxide found in bauxiteore. The products are aluminium sulphate and water. Bauxiteore is 30% to 75% aluminium oxide.
a) Write a balanced equation for this reaction.
b) What is the maximum mass, in kilograms, of aluminium sulphate that could be formed from 2.3x10^3 kilograms of bauxiteore that is 62% aluminium oxide?
