Computer The. Analysis of Alum 158 After a compound has been synthesized‚ tests should be carried out to verify that the compound fonned is indeed the compound desired. There are a number of tests that can be perfonned to verify that the compound is the one desired. In Experiment 15A‚ you prepared alum crystals‚ KAl(S04)z·12H 20. In Experiment 15B‚ you will conduct a series of tests to detennine if your crystals are really alum. The first test is to find the melting temperature of the

Alum Synthesis: The Chemical Process of Recycling Aluminum Introduction By recycling aluminum cans‚ the costs and energy savings are dramatically more resourceful and efficient than producing aluminum from what it is naturally found in‚ bauxite ore. The process of recycling aluminum to produce potassium aluminum sulfate‚ a common alum‚ will be done through a serious of chemical reactions. Through this reaction‚ percent yield will be determined. Materials and Methods The mass of a 250 mL

PREPARATION OF POTASH ALUM [(K2SO4.Al2(SO4)3.24(H2O) Aim: To prepare a pure sample of potash alum. [K2SO4.Al2(SO4)3.24H2O] Principle: Potash alum is prepared by dissolving an equi molar mixture of aluminum sulphate and potassium sulphate in minimum amount of water containing a little amount of sulphuric acid and then subjecting the solution to crystallisation; octahedral crystals of potash alum separate out. Apparatus required: Beaker (100 ml) Trough Funnel Wire gauze Conical

This experiment is used to perform a series of synthesis reactions that convert aluminum foil to alum. Alum is used in cooking‚ to treat wastewater‚ and is used in common deodorant. In this lab a series of four reactions will occur to yield alum. Calculations: Aluminum foil: 0.5035 grams Alum & Watch Glass: 21.7691 grams Watch Glass: 15.1560 grams Alum: 6.6131 gram Theoretical Yield of Alum: 2Al(s) + 2KOH(aq) + 4H2SO4 + 22H20 -> 3H2(g) + 2KAl(SO4)2 + 12H2O(s) 0.5035gAl x 1molAl/

Analysis of Alum AlK(SO4)2*12H2O: Determining the Melting Point and Water Hydration PreLab Questions: 1. When measuring the melting point‚ it is best to heat up the sample slowly so that the alum sample would be the same temperature as the water. The sample also needs time to melt. 2. 0.787g Na2CO3 1.336g H2O Moles of Na2CO3 = 0.787/106 = 0.00742moles Moles of H2O = 1.336/18 = 0.0742 Molar Ratio = 10 moles of H2O‚ 1 moles of Na2CO3 Abstract: The purpose

PREPARATION OF POTASH ALUM FROM SCRAP ALUMINUM Introduction Aluminium because of its low density‚ high tensile strength and resistance and resistance to corrosion is widely used for the manufacture of aeroplanes‚ automobiles lawn furniture as well as for aluminium cans. Being good conductor of electricity it is used for transmission of electricity. Aluminium is also used for making utensils. The recycling of aluminium cans and other aluminium products is a very positive contribution to saving
