The oxidation of ethanol

The purpose of this experiment is to oxidize ethanol and then to test the product to determine whether it has been oxidised to ethanal or oxidised to ethanoic acid. Method We added 6cmi?? of water to a pear-shaped flask, then added 2cmi?? of concentrated sulphuric acid, and set up the apparatus as shown below, but… View Article

Top-pan balance

If we look at Tahmid’s lowest concentration, 1cm3 was produced. Then when we look at the highest concentrations on both, 0. 417 for my results and 5. 208 for Tahmid’s, 11. 33 cm3 and 10. 67cm3 f carbon dioxide was produced respectively. Both of the graphs had a positive correlation, the total of carbon dioxide… View Article

Practical on Enthalpy Changes Between Acids and Bases

Introduction All life on earth depends on the transfers of energy in chemical reactions. So that measurements can be made when energy is transferred during chemical reactions, that have to be carried out under controlled conditions. A special name is given to process where energy is transferred and exchanged with the surroundings, when taking place… View Article

The effect of different factors on egg white

As the title suggests I am going to investigate the effect of various factors in egg white. And as all of us know that egg meals are rich in proteins and that why we feed them to small children. But not all the parts of the egg have the same amount of proteins in them… View Article

Acid Rain Investigation

Background information: o There are many different kinds of erosion but acid rain or else wind erosion are the two main types which could have eroded the marble statue which was positioned in the garden close to the industrial site. o Acid rain is made up from of a cocktail of different acids e.g. sulphuric… View Article

The effect of acid rain on building materials

Due to dissolved carbon dioxide rainwater is naturally acidic in the form of the weak carbonic acid. However gases such as sulphur dioxide and nitrogen oxides cause acid rain, which is responsible for the corrosion of buildings and damage to the wildlife. The burning of fossil fuels releases these gases into the atmosphere when the… View Article

Analysis of Neutralizing Power of Anti-acid Tablets

Chemical Principles: Neutralization occurs when acid and alkali are mixed together. It involves the reaction between H+ and OH-, forming salt and water. The properties of acid and alkali will be cancelled out in the process of neutralization. In our stomach, the gastric juice inside contains concentrated HCl (at about pH2). When excessive amount of… View Article

Determining the Concentration of Sulphuric Acid

I am going to plan an experiment to determine the accurate concentration of sulphuric acid. It is thought to have the concentration between 0.05 and 0.15 moldm-3. I will be provided with a solid base which is anhydrous (powder) sodium carbonate (Na2CO3). To find the accurate concentration I will titrate the sulphuric acid against the… View Article

Sodium Thiosulphate and Hydrochloric Acid Coursework

In this experiment I will be seeing how the concentration of Sodium Thiosulphate, Na2S2O3, and Hydrochloric Acid, HCl, affects the rate of the reaction. In this reaction the solution turns milky yellow as sulphate is displaced and forms a solid precipitate. Na2S2O3 (aq) + 2HCl (aq) ———-> 2NaCl (aq) + H2O (l) + SO2 (aq)… View Article

Experiment to find the concentration of the ethanedioic acid

I can use a gas collection to find the overall concentration of the acid mixture, and as I already have the concentration of H2C2O4 , I can simply minus that from the total concentration to get the concentration of the H2SO4. Both strong and weak acids will react with a metal, therefore I will react… View Article

Pickles and Fermentation

The word pickle derives from the Dutch word pekel, meaning brine or a salt and water solution for pickling. Pickles are cucumbers put through the pickling or brining process. Pickling process dates back to ancient times that was and is still used in persevering food by anaerobic fermentation in brine to make a lactic acid,… View Article

Impetigo and Topical Fusidic Acid

Dobie and Gray stated that for more than 35 years Fusidic acid – a narrow spectrum antibiotic derived from Fusidium coccineum has been used to treat infections from Staphylococcus aureus thus making it suitable in combination with another agent for systemic therapy in vitro. In spite of controversies and recommendations, the usage of topical fusidic… View Article

Litmus Milk Procedural

Litmus milk is a complex medium that can potentially distinguish many species of bacteria. Litmus milk has several components that can be metabolized: lactose (milk sugar); casein (milk protein); and litmus (a pH indicator). If lactose is fermented, the solution should turn pink. If gas is produced during fermentation, you may be able to see… View Article

Milk – Protein

Everyone has heard the saying “drinking milk helps build strong bones”, but is this really true? According to Walter C. Willett, chairman of the Department of Nutrition at the Harvard School of Public Health, “There’s no solid evidence that merely increasing the amount of milk in your diet will protect you from breaking a hip… View Article

Chemistry of Coffee

Before coffee is roasted, it is referred to as “green coffee”. The green coffee is primarily made up of caffeine, lipids, carbohydrates, proteins (amino acids), and organic acids (although inorganic acids exist in coffee as well). These groups are quite stable in the green phase, and it is the carbohydrates, proteins, and acids that will… View Article
