Experiment 5: Percent Water in a Hydrated Salt Chemistry 1300 Instructor: 2/8/12 Abstract: The purpose of this experiment was to determine the percent by mass in a hydrated salt‚ as well as to learn to handle laboratory apparatus without touching it. The hydrated salt‚ calcium carbonate‚ was heated with high temperature to release water molecules. Gravimetric analysis was used in this experiment to determine the percent by mass of water in a hydrated salt. The hypothesis of this experiment was

Epsom salt have many uses‚ including use as bath salts‚ as a laxative and as a plant nutrient. Epsom salt contains hydrated magnesium sulphate which has the formula MgSO4.xH2O. Experiment to find the value of x in a pure sample of hydrated magnesium sulphate. The method i will use is heating a known mass of magnesium sulphate to remove the water of crystallisation. x is found by weighing before and after heating to find the mass of the water then using the moles calculations to find x.
