Analysis of Alum AlK(SO4 )2 . 12H2O AP Chemistry Lab # 5 INTRODUCTION Every compound has a unique set of chemical and physical properties. To identify a compound with certainty‚ experiments have to be conducted in order to verify these properties. Such kind of analysis is usually performed when a compound is synthesized‚ and whether the compound is indeed the compound desired needs to be ascertained. The main purpose of the experiment is to analyze alum‚ AlK( SO4 )2

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

Purpose: The purpose of this experiment is to determine the number of moles of water molecules of crystallization of a sample of hydrated Barium Chloride. This can be calculated using Gravimetric Analysis and to indirectly determine the percent composition of a hydrate by taking advantage of its chemical properties. Introduction: Gravimetric procedures are analytical methods in which the results are determined from the masses of starting materials and products. These methods

toxins and more. Something I have been struggling with recently is making sure I drink enough water. Sometimes I am forgetful‚ and other times I would rather just drink sweet tea or a soda. None of my excuses are good enough though. I can tell a difference when I am hydrated in how I feel and in my appearance. When I am hydrated‚ my skin glows‚ I have more energy‚ and it makes a world of difference when I run. Now that I have reminded you why staying hydrated

Alum Lab Conclusion The purpose of this laboratory was to use two different techniques to attempt to identify the melting point and the mole ratio of hydrated water to anhydrous aluminum‚ potassium‚ and sulfate of AlKSO4. The hypotheses were: if the alum was put in a capillary tube the melting point of alum will be able to be determined; and the water of hydration in alum crystals will be possible to determine if the alum is heated with a Bunsen burner.

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

Analysis of Alum‚ AlK(SO4)2・12 H2O Partner: Cindy Date: Sep 15‚ 2011 Purpose: The purpose of this experiment is to verify the identity of the alum by finding the properties of the substance; melting point and mole ratio of the water to the anhydrous. Every substance has unique characteristics which help to determine the identity of it. The actual values of the properties can be compared to the experimental values. In real life‚ this can be used to determine the unknown medicines. Hypothesis:

The Formation of Alum Experiment 4 Introduction In an increasing population the need for land fields are as well increasing daily. Better yet‚ rather than dumping off trash is to instead recycle aluminum cans for a more efficient society. In this lab we will show how aluminum cans react to form alum. Materials and Methods The first step of the lab is to measure the mass of 250 mL beaker‚ once you have done this add .9 to 1.2 grams of aluminum can pieces to the beaker. Take the mass once
