The book “Purity of Heart” is a composition of letters written by the founder William Booth. Originally‚ these letter were shared in weekly Salvation Army gatherings to help Salvationists continue in Holiness‚ then later they were put in book form. Holiness is viewed as synonymous to a “pure heart; this is define in chapter eight‚ by William booth. The book is divided in ten chapters that are interrelated and build upon each other. It begins by defining purity of the heart in general terms. Next

EXPERIMENT #1: THE PURITY AND PURIFICATION OF SOLIDS MELTING POINTS ABSTRACT Melting points of different mixtures of naphthalene and biphenyl were examined in this lab. Samples of these various mixtures were collected and tested by different individuals in the lab in order to find the eutectic point of biphenyl. Unknown substances were then tested using the mixture melting point method in order to determine their identities. INTRODUCTION The melting point of a solid is the temperature

The Purity and Purification of Solids Melting Points CH-337 Abstract: The purpose of this experiment was to find the eutectic point for the mixture of naphthalene and biphenyl. This was done by measuring the melting point of both pure substances and five mixtures of different ratios. The purpose of the second section was to identify an unknown sample by measuring its melting point and mixing it with two known substances and comparing them. The results suggest that the eutectic point is closest

The Fight for Food Purity Economic Botany September 29‚ 2013 Michael Pollan’s film‚ The Botany of Desire‚ opened my eyes to the complicated relationship between people and plants. Pollan opened up with the following statement: “Flowers. Trees. Plants. We ’ve always thought that we controlled them. But what if‚ in fact‚ they have been shaping us?” (Pollan‚ PBS) I paused the film and took a few minutes to let this soak in. I was always under the impression that we

Acid (ASA or Aspirin) Background Salicylic acid is a phenol as well as a carboxylic acid. It can therefore undergo two different types of esterification reactions‚ creating an ester either with the hydroxyl or with the acid. In the presence of acetic anhydride‚ acetylsalicylic acid (aspirin or ASA) is formed. Correspondingly‚ an excess of methanol will form methyl salicylate‚ which is also an analgesic. In this experiment‚ we shall use the former reaction to prepare aspirin. Salicylic

filtered and air dried to yield 0.45 g of sucrose (15.0 % of original Panacetin). Isolation of Aspirin: The organic filtrate was extracted through a separatory funnel with 32 mL 5% sodium bicarbonate to produce an aqueous layer and a dichloromethane layer. 7.2 mL 6 M hydrochloric acid were added to the aqueous layer until the pH was 2. The mixture was then cooled in an ice/water bath for 10 minutes. The aspirin was collected by vacuum filtration. After it dried‚ it yielded 0.93 g (30.9 % of original Panacetin)

Practical Experiment Report 11-11-2013 Introduction This experiment was designed to investigate and compare the rates at which different aspirin tablets dissolve in both Water (H2O [representing saliva]) and Hydrochloric Acid (HCl [representing the stomach’s acid]). The amount of Water and Hydrochloric Acid will be kept constant between tablets‚ and tests. Aim To investigate and compare the rates at which different Aspirin Tablets dissolve. The different kinds of Aspirin tablets are: Enteric

The Power of Purity A vision in white surrounded by the air of purity and near divinity was the image of a Vestal virgin. These women became synonymous with the eternal existence and safety of Rome. The representation of influence‚ devotion‚ and power were characteristics of these six women who sacrificed their sexuality and family cults to serve the Goddess Vesta and to profit from the advantages that such devotion earned. The life of a Vestal virgin was unlike that of any other Roman woman with

Synthesis of Aspirin Abstract The purpose of this experiment is to synthesize a common organic product called acetylsalicylic acid (aspirin)‚ and to become familiar with the optimum conditions needed for successful yields. Aspirin is produced from an acid catalyzed reaction between salicylic acid with acetic anhydride. The crystalline aspirin is synthesized and purified by recrystallization‚ although there is not a hundred percent yield due to sources of error. Introduction Aspirin is a medicine

Extracting NaCl from Rock Salt and assessing its purity Aim The aim of this experiment was to obtain a pure product from a solution through the processes o extraction‚ filtering and evaporation. Introduction Extraction is used when trying to separate or purify a product. For an extraction to be successful the substance used to make the solvent should readily dissolve. The substance used in this practical was rock salt. The liquid used should not react with the substance that needs extracting
