中文Aspirin & Salicylic Acid – Ferric Chloride Complexes
The major hydrolysis product of aspirin is salicylic acid, which can form coloured complex with neutral FeCl3. Aspirin is incapable of forming this complex. Explain this process. First marketed under the trademark Aspirin® in 1899,acetylsalicylic acid quickly attained a worldwide reputation as anon-prescription pain relief drug. Even today it is one of the most widely […]
Benzene
I. Medical history: How is it used in medicine and what disease it is used against. Benzene is a common air pollutant and also is a very stable compound. Benzene, in its original form is known to produce neurotropic symptoms as well as hematological abnormalities and malignancies. It is also a known carcinogen. Benzene, at […]
Explain the Uses of an Organometallic Compound
The term Organometallic arises from the covalent bond existing between a carbon atom and a metal atom and as the name suggests, it is a compound that is partly organic and partly metallic. There are, however, compounds containing metal to hydrogen bonds and also other compounds containing non-metallic atoms bonded to carbon which are classed […]
Quantitative Infrared Spectroscopy used as a tool to monitor the hydrolysis of aspirin
Rapid advances in science and medicine have led to an increase in the demand for chemical and structural information on biological and pharmacological materials. Due to its unique fingerprinting capability, vibrational spectroscopy plays a significant role in providing structural and mechanistic information through the ability that IR spectroscopy offers to identify small changes in the […]

Question 5 If extraterrestrial life did exist, the most likely place scientists would point to would be Mars. Comparatively, even though Mars with a core radius of 1700 Km compared to 3485 Km,1is smaller than Earth, it is the closest planet to Earth in terms of size and proximity to the sun. Also in common, […]
Three Component Phase Diagram of the Water-Heptane-Propanol System. Illustrate your essay with specific examples.
A convenient way of illustrating the principles governing phase changes within three component systems is to use a partially miscible liquid system. In the past, the acid-chloroform-water system has been employed as a practical example to investigate ternary systems and the miscibility gap (Wright et al., 1891; Brancker et al., 1940). However, since the status […]
Polyamines. Illustrate your essay with specific examples
Abstract The objective of this project was to synthesize a protected spermidine derivative, which is a polyamine derivative. The spermidine that was to be synthesised is a N8 protectedspermidine derivative. Other students have studied the synthesis ofN1 protected spermidine. A retrosynthetic analysis of the required N8 protected spermidine derivative of wascarried out to devise a […]
Describe the trend in the PHYSICAL and CHEMICAL properties of the CHLORIDES and OXIDES in period 3 of the periodic table (i.e. Na – Ar). Illustrate your essay with specific examples.
Introduction The chlorides and oxides of period 3 elements of the periodic table have been extensively studied and investigated and include many interesting and industrially important compounds. These compounds exhibit distinctive properties which vary widely across period 3, ranging from the use of sodium chloride in the chlor-alkali industry to produce chlorine and caustic soda […]
Azo Dye Synthesis. Illustrate your essay with specific examples.
Azo dyes form a class of compounds that are widely used as food additives as well as coloring agents in textile industry (Gordon and Gregory, 1983; Fierz-David and Blangey, 1949). They constitute sixty to seventy percent of the dyes used for industrial purposes. The term “Azo” comes from the French term “Azote” which denotes nitrogen. […]
