Sulphuric

Sulfur aerosols are very dangerous natural gases formed when sulfur melts at around fifty degrees fahrenheit that are usually released into the atmosphere at great heights. They mix with ash and other debris, forming large plumes that can travel across the sky for miles. They also go very high into the sky, spreading out in every direction. These giant plumes of sulfur aerosols form deep in the earth inside volcanoes until enough pressure and gas build up and they are injected into the air. These

react with metals, releasing hydrogen gas and leaving behind a salt they also can conduct electricity. Acids also readily give off hydrogen ions and have a pH level lower than 7. Some more common laboratory acids are Hydrochloric, Sulphuric and Nitric Acids. Sulphuric acids and water are used in car batteries as the electrolyte. Bases or alkali are a chemical that will react with acids and usually have a slimy or soapy feeling on contact with skin. Bases readily accept hydrogen ions and has a pH

Phosphate buffer (50 mM: pH 7.0): a) 6.81 g. KH2PO4 was dissolved in distilled water and made to 1000ml. b) 8.90 g. Na2HPO4. 2H2O was dissolved in distilled water and made up to 1000ml. 2. Hydrogen peroxide (30 mM): 0.34 ml 30% hydrogen peroxide was diluted with phosphate buffer (solution a) to 100 ml. Procedure: The Venous blood was centrifuged. The plasma and leucocytes layer was separated. The erythrocyte sediments were washed 3 times with isotonic NaCL. A stock haemolysate

Distinction task: Explain which steps in the procedure could reduce the final yield: Explain which steps could reduce or improve purity of the final product: Steps 1, 2,6,7,8,9,10 and 12 are all to do with measuring. This is an important factor when thinking about trying to get as much yield as possible because if the accuracy is wrong we would lose yield and therefore would reduce the final product. For example, during step one, the alcohol has to be poured into the pear shape flask. There is a

Question: should flue-gas Desulfurization (FGD) be used in all Australian coal mining power plants Acid rain is usually acidic, meaning that it will process elevated levels of hydrogen ions (low pH). It can have bad effects on buildings, plants, or even animals. Acid rain is caused by emissions of sulfur dioxide and nitrogen dioxide, which will react with water molecules in the atmosphere which produce acids and causes acid rain. Acid rain is usually cause by a chemical reaction which begins

- In the process of decaying of organic matter some bacteria will produces hydrogen sulphide as a waste product which will oxidise, forming so2. - Phytoplankton release dimethyl sulphide (DMS) into the atmosphere, when this is oxidised it forms sulphuric acid. NOx, natural: - Lightning activity generates high temperatures to allow oxygen and nitrogen to combine. Nitric oxide combines with oxygen in the presence of lightning. The no will then slowly combine with oxygen in the atmosphere to form

Subsequently, when the 2mL of sulphuric acid was added to the pink solution, the solution immediately returned clear in colour, therefore highlighting that the solution was acidic. Station seven can be clearly identified as a neutralisation (acid, base) reaction, as an acid and base has reacted together to form salt and water. The reactants, sodium hydroxide and sulphuric acid reacted together to produce sodium sulphate and

contribute to sulphur dioxide, sulfates and sulfuric acid forming in atmosphere. Then it could potentially lead to premature deaths in the region(,). In operations of Olympic dam, majority of primary sulphur dioxide emissions are converted into sulphuric acid in the acid plant that reduce the environmental effect on air quality. Other emissions consist of oxides of nitrogen, carbon monoxide (CO), lead (Pb) and fluoride, carbon disulphide (CS2), Volatile Organic Compounds (VOCs) and Polycyclic Aromatic
