An Experiment to find the Concentration of a Sample of Acid Rain Plan Aim When a metal is extracted from its ore often sulphur dioxide is produced. When sulphur dioxide is dissolved in water it forms a strong acid called sulphuric acid. Sulphuric acid is often sold as a useful by-product‚ but also gets into the water cycle and forms acid rain. In this experiment‚ I have been given a sample acid rain of concentration between 0.05 mol dm-3 and 0.15 mol dm-3 and my aim is to find out exactly what

isomers of α-phenylcinnamic acid. This was accomplished by refluxing benzaldehyde‚ phenylacetic acid‚ acetic anhydride and triethylamine as a base. The chemical equation of a Perkin Reaction can be seen below. The reaction mechanism for the synthesis of α-phenylcinnamic acid is shown below: Results: Theoretical Yield Therefore‚ phenylacetic acid is the limiting reagent. Table 1.

hydrochloric acid will be effected if we change the concentration of hydrochloric acid. Introduction In the experiment the magnesium reacts with the hydrochloric acid to create magnesium chloride and hydrogen. The balanced formula for this is: Mg(s) + 2HCL(aq) MgCl2(aq) + H2(g) Magnesium + hydrochloric acid Magnesium Chloride + Hydrogen Magnesium will react with hydrochloric acid‚ because it is higher in the reactivity series than hydrogen. The magnesium displaces the hydrogen in the acid‚ so it forms

Global Bio Succinic Acid Market published at Truemarketresearch.com The U.S. Department of Energy (USDOE) considers succinic acid as one among the top twelve chemical building blocks. Succinic acid‚ as a platform chemical‚ is growing in demand in various applications. However‚ consumption of petroleum based succinic acid‚ as an intermediate‚ in manufacturing various chemicals‚ is limited due to its volatility of price and carbon footprints. These concerns led to the discovery of biological manufacturing

Acid rain is any type of precipitation that has high acid content. This precipitation can be wet (rain‚ snow‚ or fog) or dry (gases or acidic salts). Normal rain is slightly acidic with pH 6.5 but we call it acid rain when it is pH is between 2 and 5.5. It is formed by chemicals created by the burning of fossil fuels‚ power plants‚ factories and auto mobiles. These chemicals are sulfur dioxide and nitric oxide. Sulphur dioxide and nitric oxide react with water in the atmosphere and eventually fall

How to Reduce Lactic Acid Build up in Muscles Understanding Lactic AcidReducing Lactic Acid During a WorkoutReducing Lactic Acid Through Your Diet Edited by LC108‚ BR‚ Jacob‚ Vahab2121 and 5 others Lactic acid is released into the muscles when they have used up their normal energy stores but still have intense energy needs. Small amounts of lactic acid operate as a temporary energy source‚ thus helping you avoid fatigue during a workout. However‚ a build up of lactic acid during a workout can

Acid rain is a very big pollution problem in the world. It has killed fish and other aquatic life in many lakes and streams. It harms human health‚ disfigures monuments and erodes buildings‚ and‚ along with other pollutants‚ threatens forests. The story of acid rain can be compared to the plot of a science fiction movie. In the 1950s an invisible force begins to destroy lakes and rivers‚ killing trout and salmon. By the 1960s it is harming the waters of eastern Canada and the northeastern United

acid rain Acid rain is rain or any other form of precipitation that is unusually acidic. It has harmful effects on plants‚ aquatic animals‚ and infrastructure. Acid rain is mostly caused by human emissions of sulfur and nitrogen compounds which react in the atmosphere to produce acids. In recent years‚ many governments have introduced laws to reduce these emissions. Emissions from volcanoes and those from biological processes that occur on the land‚ in wetlands‚ and in the oceans account for the

1. Omega 3 fatty acids and Alzheimer’s disease Omega 3 fatty acids and Alzheimer’s disease how do they relate to one another? I have found in my research that omega 3 has been proven to show a delay in the process of Alzheimer’s disease and also has many other health benefits. This is my findings in doing my research. Although no one knows what causes Alzheimer ’s disease‚ many research studies indicate that those who regularly eat fatty fish or who supplement with fish oil have a lower
