EXERCISE 11 Synthesis of Aspirin (Acetylsalicylic Acid from Salicylic Acid) RAQUID‚ Rency J Group 5 18L I. Introduction Due to the demand of certain reagents in the laboratory in order to perform and conduct further experiments or produce essential compounds‚ chemists continuously develop organic synthesis. This process aims to prepare and synthesize desired organic compounds from commercially or readily available ones by providing the simplest route in synthesizing the compound

fatty acid chains (carboxylic-acids). These undergo a condensation reaction to form a triglyceride-molecule and the by-product‚ three molecules of water [1]. The general structure of triglyceride can be presented below: Where R‚ R’ and R’’ represent particular carbon fatty acid chains. The fatty acid composition is the most important characteristic of the triglyceride. The physical and chemical properties of particular triglycerides depend on the nature and arrangement of these fatty acid residues

Amino Acids Amino acids are biologically organic compounds containing amine and carboxylic acid functional groups‚ usually along with a side-chain specific to each amino acid. The elements that are key of an amino acid are carbon‚ hydrogen‚ oxygen‚ and nitrogen. There are about 500 different kinds of amino acids found but we recognize 23 of the amino acids that are known‚ they are classified into three groups‚ essential semi-essential‚ and non-essential. Each amino acid has unique characteristics

Characteristics and Properties of Amino Acids Introduction: Each amino acid has at least one amine and one acid functional group as the name implies. The different properties result from variations in the structures of different R groups. The R group is often referred to as the amino acid side chain. Amino acids have special common names‚ however‚ a three letter abbreviation for the name is used most of the time. A second abbreviation ‚ single letter‚ is used in long protein structures.Consult

ANTACID WILL NEUTRALIZE STOMACH ACID THE BEST AND IS MOST COST- EFFECTIVE? Description This experiment was conducted to find out how effective different types and brands of antacids are at neutralizing acid. I also looked at the cost of each product in order to determine if my hypothesis would be correct. The experiment was done using 4 brands of antacid‚ Pepto-Bismol‚ Gaviscon‚ Tums and Tagamet. Hypothesis All the antacids will neutralize different amounts of acid but the most expensive one

Experiment on Metals Aim-To find out which of these metals will be most reactive with hydrochloric acid‚and plan an investigation to test it out.The Metals given:Calcium‚Aluminium‚Iron‚Magnesium and Zinc. Prediction-I predict that the metal will be the most reactive with hydrocholoric acid is calcium because calcium is in Group 2 which is the alkaline earth metals in the periodic table and because calcium is at the extreme left side of the periodic table and as you go across a period‚the element

I will also mention the time which was taken in the experiment‚ to see how fast the hydrochloric acid took with indigestion tablet with different concentrations. Indigestion tablets are alkali and they are used for to neutralise the excess acid in the stomach. Indigestion Tablet Indigestion is caused by excess acid in the stomach. The tablets neutralise some of this Acid and this is known as ‘Neutralization’ since it neutralizes the acid. In this

Lab 5 Acid/Base Extractions Introduction The purpose of this experiment is to separate either the organic base (amine) or organic acid (carboxylic acid) from a mixture that contains inorganic impurities (salt) by performing a liquid-liquid extraction and then taking a melting point. Key Experimental Details and Observations Our starting material‚ Compound B‚ was a fine white powder and weighed 0.535g. The final product was a shiny white sheet that resembled acrylic paint and weighed 0.109g
