Sulphuric acid

The main purpose of this experiment is to decipher whether acid is friend or foe? Acid is a particular substance with chemical properties including; turning litmus red, corroding metals, and neutralizing alkalis (bases). In the late 1800s, the Swedish scientist Svante Arrhenius suggested that acids are chemical compounds that, when dissolved in water, give a solution with a hydrogen ion activity greater then water, a pH less than 7.0. A base however is any compound that, when dissolved in water

Acid Rain: Effects and Prevention Yulia A. Bespalova Abstract: Acid rain is a serious environmental concern that implies a serious responsibility for all inhabitants living in a particular ecosystem. Acid rain is a mixture of sulphuric and nitric acids, which formed due to sulphur and nitrogen oxides emissions. The soil acidity is increased in the result of interaction of these acids with components of the atmosphere. Acidification of soil leads to leaching away nutrient cations from the soil and

Acid rain has proved to take a huge toll on Ontario’s ecosystem. However, in this section of the textbook, factors such as effects of acid rain, assessing the effects on soil and water, acidity levels and others, contribute to the main topic of acid rain in an ecosystem. To begin, the downpour of acid rain is due to the emissions from human activities that contain different pollutants/invisible gases that can be very harmful to the environment. In other words, substances containing nitrogen and Sulphur

Introduction 1.1 Purpose of the Report The purpose of this investigation is to research aspects of water quality such as guidelines for water quality, water quality parameters, contaminants that effect water quality, water quality tests and catchment area influences. Samples from the Dee River, from above and below the former Mount Morgan mine site, will be tested and compared in terms of pH level, conductivity and water hardness. The links that exist between pH levels and water hardness will also

acetylsalicylic acid (aspirin), thus becoming familiar with synthetic chemistry tools and techniques. Introduction1 Organic molecules can be classified based on the functional groups that they possess. One of these classes is esters, which are produced from an acid and an alcohol as shown in the following figure. Figure 1: Reaction of a carboxylic acid and an alcohol to form and ester.2 Based on the above reaction, a wide variety of esters can be formed since there are so many acids and alcohols

Acid rain is a result of air pollution that includes any form of precipitation with acidic elements like nitric or sulphuric acid . Many different chemicals are produced when any type of fuel is burnt. The smoke that is emitted from a car exhaust does not only contain the sooty grey particles that is visible to eyes but also contains many harmful invisible gases, which can be dangerous to the environment. Polluting gases are produced due to combustion as factories, cars and power stations all burn

As the Port Pirie smelter continues to produce refined lead, copper, and gold, amongst other metals, concern has been raised regarding the emissions and their immediate effect on the population and the surrounding environment (Zinifex Limited, 2007). This establishment is the largest operating lead smelter in the world with a total of 747 employees (Portpirietransformation.com, 2016). Due to its location on the shore of the Spencer Gulf, the adjacent port, ships in unrefined ores from around the

Acids are part of our everyday life. Citrit acid is found in lemons, limes, and oranges. Carbonic acid is found in soda pop. However, acidic gases natuarlly occur in the atmosphere. This acidic process can be made from plants and animals (“Acids in the Environment,” 2011). Generally, rain is is inherently acidic. Acid rain though, is exactly the same excerpt for a slight increase in acidity. Neither of them cause burns, however. There are many different types of acid rain, the best known are

10 PRE-SACE CHEMISTRY PRACTICAL DESIGN ASSESSMENT "ORGANIC vs INORGANIC ACIDS" Instructions: Students will be supplied with a range of acids including, sulphuric, ethanoic, hydrochloric, citric acids. From this list they are to choose an organic and inorganic acid to compare. Students must design and conduct a simple experiment to measure the different reaction rates of the acids. Only the following materials will be made available to students; Ph Paper Ph sensor and data logger Litmus solution
