Preparation of Sodium Chloride through titration Abstract: acid-base titration is a technique commonly used to determine the moles of acid in a sample by adding a known volume of strong base of a known concentration. The strong base provides the hydroxide ion‚ to react quantitatively with the acid. The point at which the acid is completely and exactly consumed the known quantity of base is called the equivalence end point and is signalled by a colour change in the solution (end point). This colour

The purpose of our experiment was to synthesize aspirin from acetyl anhydride‚ salicylic acid‚ and sulfuric acid. And then determine the relative purity of the synthesized sample. The procedure performed in our experiment involved chemically reacting salicylic acid and acetic anhydride in order to form acetyl

Aspirin Background Aspirin Aspirin‚ or acetylsalicylic acid (ASA) is a salicylate drug‚ and is generally used as an analgesic (something that relieves pain without producing anaesthesia or loss of consciousness) for minor aches and pains‚ to reduce fever (an antipyretic)‚ and also as an anti-inflammatory drug. Aspirin works by prohibiting biological substances such as prostaglandins. Many different prostaglandins exist in the human body each serving a plethora of physical functions.

Monica Perez Experiment 8: Acetylsalicylic Acid Experiment 01/25/2013 CHM Lab- 2211 Sec 0016 Instructor: Jennifer Reed Introduction: Commonly used as Aspirin‚ acetylsalicylic acid is an analgesic (pain reliever)‚ which is one of the products of the esterification reaction between salicylic acid and acetic anhydride. This esterification occurs since the hydroxyl group from the salicylic acid reacts with acetic anhydride to form an ester. In this experiment‚ we will be able to recreate

the percentage composition of the label (50% paracetamol‚ 40% aspirin and 10% sucrose) matches that of the percentage composition of the powder by following 10% ranges of each component in the powder. I am going to do this via a number of methods including vacuum filtration‚ heating‚ extraction and evaporation. Experimental method: The experiment was done in three parts: firstly the separation of sucrose‚ then the separation of Aspirin and the isolation of the unknown component. 1. Separation

describe the functioning of Aspirin in our body‚ its various properties to fight pain‚ and its evolution over the years. Littlejohn describes how Aspirin claimed celebrity status as one of the world’s most popular‚ inexpensive painkillers by relieving headaches‚ sprains‚ blows‚ burns‚ swelling and fever. Furthermore‚ she added that Aspirin could also be used to reduce the risk of stroke and heart attack. The author supports the main idea by describing how the aspirin when taken with a modest stream

! Isolation of the Components of BC Powder Introduction Aspirin‚ Caffeine and Salicylamide were extracted from an over-the-counter pain reliever (BC Powder). These components were separated by manipulating their solubilities by adjusting the acidity and basicity of the solution. By doing this‚ the three components were forced into conjugate acid (or base) forms‚ causing selective solubility in either an aqueous or organic solvent. These layers were then separated by use of a separation funnel
