the form of Mn2+ that promotes oxidation. The sulfuric acid added to the titration flask acts as a proton donor for the solution readily giving up protons. Since the oxalic acid is not a strong acid and does not dissociate well, but is still needed in the reaction to form carbon dioxide, the addition of a strong acid, sulfuric acid, supplies the protons needed for the reaction. Procedure: Obtain and zero two burets, one containing .0500M oxalic acid and the other containing the permanganate solution
The experiment we did was Copper Cycle. We reverted the copper to its elemental form after a chain of reactions. We performed a series of reactions, starting with copper metal and nitric acid to form copper (ii) nitrate. Then we reacted copper with sodium hydroxide, sulfuric acid, nitric acid and zinc to form precipitates. In conclusion our percent recovery was 40.38%. Introduction: The purpose of this lab was to to cycle solid copper through a series of chemical forms and return it to its original

Incident at the SJV Refinery, Case Study Curtis Acree Columbia Southern University As an emergency response coordinator for a refinery it is vital to understand what hazards are associated with the products found in a crude oil refinery. Routine and non-routine maintenance will need to be done in order to maintain a working and operating oil refinery. This can create complicated situations or scenarios, because numerous contractors may be brought in for different repairs. This can lead to
Background and Strategic Issues In June 1979 American Chemical Corporation, a large diversified chemical company, acquired Universal Paper Corporation. When working on the deal structure, both the federal government and Universal’s management team created various legal constraints, arguing that if the acquisition would take place, American Chemical Corporation would become the largest sodium chlorate producer, violating U.S. antitrust laws and the Clayton Act. With that being said, American Chemical

Native Copper and copper ore Since copper is relatively unreactive lumps of pure copper can be found under the ground. 400 tones of pure copper was the most anyone has found but native copper usually isn’t mined as it is too hard to find and won’t make enough of a business. Copper is found all over the world but mostly in ores such as chalcopyrite, malachite and covellite. Chile, USA, Peru, China and Australia are all big contributors of copper. Extraction process There are ranges of different
Purpose/Introduction: In this experiment, four elimination reactions were compared and contrasted under acidic (H2SO4) and basic (KOC(CO3)3) conditions. The acid-catalyzed dehydration was done on 2-butanol and 1-butanol; a 2ᵒ and 1ᵒ alcohol, respectively. The base-induced dehydrobromination was performed on 2-bromobutane and 1-bromobutane; isomeric halides. The stereochemistry and regiochemistry of the four reactions were analyzed by gas chromatography (GC) to determine product distribution (assuming
Medicine During the Elizabethan Era The medicinal practices and problems of the Elizabethan Era were very important to the people, although they are very different from those of today. There were many different beliefs and diseases, like the Plague. Medicine was not an exact science and was related to Alchemy (Chemistry). Here, some of the many practices and beliefs of the Elizabethan Era will be discussed. One of the most widely known and important of the beliefs was the humours. It was
The phenol-sulfuric acid method is a simple and rapid colorimetric method to determine total sugar in a sample. The method detects virtually all classes of carbohydrates, including mono-, di-, oligo-, and polysaccharides. It is one of the most versatile, relatively easy and cheap approaches for determination of carbohydrate concentrations is the colorimetric method based on reaction between hydrolysed carbohydrate solution and a colouring reagent that develops colour that is detectible in the visible
ackground Sulphuric acid is considered to be one of the strongest acids. It was first discovered in the 800A.D by an Islamic chemist by the name of Jābir ibn Hayyān. It is also the world’s most important industrial chemical, often called the “oil of vitrol”. It is a diprotic acid and is very corrosive and it able to eat through many organic substances and the acid is soluble in water at all concentrations. One of the reason as to why sulphuric Acid is important to the chemical industry because it
Rates Of Reaction Investigation Plan: This experiment is planned to investigate the rate of reaction when mixing Copper sulphate (CuSO4) with Zinc powder (Zn). My plan is to see what happens before, during and after the reaction takes place. I will need the following equipment to carry out this investigation: Ø A 50ml marked measuring tube Ø A digital precision scale Ø 600ml of copper sulphate Ø A digital thermometer Ø A pot of Zinc powder Ø A sandpaper (to sand the Copper
Investigation to Identify the Formula of Hydrated Copper Sulphate Aim: I plan to investigate the formula of Hydrated Copper Sulphate and, more importantly, what x stands for in the formula (CuSO4.xH2O). This will tell me how many molecules of water surround each molecule of Copper Sulphate. To do this I plan to work out the amount of water a set mass of Hydrated Copper Sulphate loses when it becomes anhydrous. I will work this out by measuring the difference in mass between the two states
are burnet sulphur dioxide is releases and when it combines with water vapour in the air dilute sulphuric acid is the product. Nitrogen oxides combine in a similar way to produce nitric acid. The result is acid rain. The acid rain chemically weathers materials away by decomposing the minerals. London is widely known for burning large doses of fossils fuels increasing the amount of acid rain. This rain has then fallen on buildings such as St. Paul’s Cathedral and increased chemical weathering
Catalysts speed up the rate of reaction and remain chemically unchanged or being used up in the process, and are widely used in industry. Enzymes are biological catalysts made up of proteins, and can be used a lot in industry since they operate best close to room temperature and pressure which can be maintained in industrial processes. Catalysts will speed up rate of reaction and can also be used to change properties of a product to increase it’s usefulness – it can turn light, bendy poly(ethene)
Biology: Separation of Proteins Lab Report 1: Separation of Proteins Abstract/Summary: “Proteins account for more than 50% of the dry weight of most cells, and they are instrumental in almost everything organisms do” (Campbell, 1999). The significance of proteins to the continuation of our biological systems is undeniable, and a study of how to quantify proteins seems an appropriate introduction to our studies of biology. In order to study proteins we must first know how to separate then quantify
