    Calcium is one of the most abundant element in the earth’s crust at number 5. Calcium has a very high chemical reactivity so it is never found as an uncombined state in nature. It is a silvery-white metal and it is in the alkaline earth family. Calcium is needed for blood clotting and controlling cell responses in nerves and muscles.Ninety-nine percent of the calcium in the human body is in our bones and teeth. Bone tissues are renewing themselves constantly and to do that they have to build new

    The solubility of calcium hydroxide Aim: to find out the solubility of a substance that only partially dissolves in water. Method: place about 100cm3 of distilled water in a flask and add about one spatula of solid calcium hydroxide. Stopper the flask and shake well for one minute. Leave to stand for at least 24 hours. Titrate 10cm3 samples against 0.05 mol dm-3 hydrochloric acid solution using methyl orange as an indicator. Obtain enough results to calculate an accurate average‚ and then

    Date: October 29‚ 2014 Title: Thermometric Titration Purpose: To determine the concentration of sulphuric acid by thermometric titration Background Information: A thermometric titration is a titration technique where the endpoints of the reaction are located from the enthalpy change between the reagents. In thermometric titration we make use of the fact that reactions in solution are accompanied by temperature changes and thus it is possible to follow the course of the reaction with a thermometer

    oxidizing agent. In this lab‚ a solution of KMnO4‚ an oxidizing agent‚ will be standardized by titration with a solution containing a known concentration of iron (II) ions‚ (Fe+). The concentration of oxalic acid solution will be determined by titration with the MnO4- solution that had been standardized first. The purpose of this lab is to standardize a solution of potassium permanganate by redox titration with a standard solution of iron (II) ions. A solution of oxalic acid is then titrated with the
