Title Determine the concentration of a limewater solution Introduction In this coursework, the objective is to plan and design an experiment and choose a range of appropriate equipment and apparatus, in the lines of normal laboratory apparatus and indicator solutions, which will allow me to find the concentration of a limewater solution. 100 cm3 of limewater is provided, which has been made such that it contains approximately 1g dm-3 of calcium hydroxide. Indicator solutions are also provided. Hydrochloric acid of concentration 2.00 mol dm-3 is also available, however it is too concentrated to be used and so needs to be diluted. THE USE OF ANY OTHER CHEMICAL IS FORBIDDEN. Aim To propose an experiment that will allow me to establish the concentration, in g dm-3, of the limewater as precisely as possible. The formation of limewater Heating calcium carbonate, CaCO3, produces quicklime, CaO. CaCO3(s) › heat › CaO(s) + CO2(g) Calcium oxide reacts violently with water to produce calcium hydroxide (slaked...
