ammonium iron sulphate and use this solution to standardise a solution of potassium permanganate. Potassium permanganate (KMnO 4 ) is a powerful oxidizing agent and is a deep purple colour. It cannot be obtained in sufficiently pure form to weigh it out accurately and make up a standard solution directly. We must titrate an approximate solution of potassium permanganate (0.02 M) against a primary standard solution‚ ammonium iron sulphate (0.1 M). Prepare the ammonium iron sulphate solution. The

tests to find out which Anion was present. From all the tests I found out that the test for bromine halide worked and the test for sulphate also worked. Conclusion In conclusion I found out that the ions present in my sample where sodium‚ sulphate and bromine. The Cation was sodium and the Anions where sulphur and bromine this means that my sample was sodium sulphate or sodium bromide. Evaluation My experiment went very well but if I could redo this I would make some changes. The Mummion

EXPERIMENT 1: WATER CRYSTALIZATION OBJECTIVES: To determine the percentage of water in aluminium sulphate hydrate To calculate the water of crystallization for aluminium sulphate hydrate To prove that a hydrate solution will lose some of it mass after heated INTRODUCTION A hydrated salt is a crystallize salt molecule that is weakly attached to a certain number of water molecules. Salt is created when an acid’s anion (negative ions) and a base’s cation (positive ions) are combined to produce

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.

EXPERIMENT 4 Title: Preparation of magnesium sulphate. Date:11.02.2010 Aim: To prepare magnesium sulphate Theory: Magnesium sulfate (or magnesium sulphate) is a chemical compound containing magnesium‚ sulfur and oxygen‚ with the formula MgSO4. In its hydrated form the pH is 6.0 (5.5 to 6.5). It is often encountered as the heptahydrate‚ MgSO4·7H2O‚ commonly called Epsom salt. Anhydrous magnesium sulfate is used as a drying agent. Since the anhydrous form is hygroscopic (readily absorbs water

Copper half cells? Aim To see the relationship between increasing the concentration of Zinc ions and the voltage that is obtained from voltaic cell. The concentration of zinc ions can be directly manipulated by changing the concentration of a zinc sulphate aqueous solution‚ and the voltage will be measured using an electronic voltmeter. Background Information A voltaic cell produces electrical energy as a result of a spontaneous redox process. The electron transfer characteristic of such a process
