Oxidizing agent

monoclinic and orthorhombic crystals showed only one doublet on the spectrum in phases of high and low temperatures. The compound has photosensitive characteristics, it possesses bioelectric chemical properties, but they are poorly oxidized by common oxidizing reagent. The polytype of K3[Fe(CN)6] are discussed in reference to cobalt salts by x-ray diffraction and Roman scattering as well. The method of preparing Potassium ferricyanide crystals is also investigated as well. The most common…

1. EXECUTIVE SUMMARY Every organism needs food to live. Importance of food has increased enormously in case of human. With the rapid growth of the population the demand of food has also increased. Fresh and unprocessed food have very less shelf life. The increasing demand of food also increased the need of extending shelf life of foods. Different natural and chemical substances called food preservatives are being used to increase the shelf life of food which prevents microbial growth and…

be shortened in order to support life. Catalase is one of the most important enzymes in living organisms, such as animals, plants and aerobic bacteria due to its capability of decomposing hydrogen peroxide, an extremely dangerous and harmful oxidizing agent to water and molecular oxygen. Conversion of hydrogen peroxide: 2H2O2…

The reaction needs to be carried out in an acidic environment because permanganate ions in an acidic environment is a strong oxidizing agent, therefore, H2SO4 needs to be added. If permanganate solution changes colour from pink to colourless, then oxalic acid is present in the food. 2KMnO4 + 3H2SO4¬  K2SO4 + 2MnSO4 + 3H2¬O + 5[O] H2C2O4 . 2H2¬O + [O]  2CO2 + 3H2O Overall reaction:…

Discussion and Scientific Explanations Colors help most people describe what different objects look like. When white light hits an object, in most cases, the object will absorb all of the wavelengths, except for one group. This group of wavelengths is then reflected off of the objects. The cones and rods in our eyes will then pick up this wavelengths and then the brain sees them as “color”. The reason that solutions have colors is because electrons in the chemical’s 4d orbital are jumping…

I WILL QUIT TOMORROW I will quit tomorrow or this is my last one. Theses are the open statements made on a daily basis by cigarette smokers. (Brownlee and Roberts) “Without cigarette breaks, smokers could gain a month 's work each year.” Cigarette smoking has been around for decades, despite all the advertisement stating that smoking is bad for your health, people can be seen on the outside of their jobs taking a break with a pack of cigarette. I can remember taking up a pack of cigarette a…

Goods Regulations (DGR) (Sales, 2013, p. 74). The DGR classifies dangerous goods into 9 categories or classes of hazardous materials (HAZMAT): Class 1 – Explosives; Class 2 – Gases; Class 3 - Flammable Liquids; Class 4 - Flammable Solids; Class 5 - Oxidizing Substances; Class 6 - Toxic and Infectious Substances; Class 7 - Radioactive Material; Class 8 – Corrosives; Class 9 - And Miscellaneous Dangerous Goods (IATA-Hazard Labels, n.d.). Some dangerous goods are forbidden for carriage on passenger…

accumulated over the past 2 decades has suggested that enhanced formation of free radicals and oxidant species symbolizes a key pathophysiological mechanism of cardiovascular dysfunction and organ damage during sepsis (Pacher et al., 2007). Among such oxidizing agents, the powerful oxidant peroxynitrite has received particular interest as an essential mediator…

Introduction: Enzymes are biological molecules that act as a catalyst to significantly speed up the rate of the chemical reactions that take place within cells without being used up in the process. According to the website, www.ducksters.com, “enzymes are special types of proteins. Like all proteins, enzymes are made from strings of amino acids. The function of the enzyme is determined by the sequence of amino acids, types of amino acids, and the shape of the string.” Along with this we need to…

initiator gives TEFLON • PROPERTIES  Teflon is linear polymer with a high degree of crstallinity  Its flow temperature is high  It is practically insoluble in all solvents  It is chemically inert and not attacked by acids, alkalis, oxidizing and reducing agents  It is not wetted by oil or water  It has high resistance to impact wear and tear  It is thermally stable and has a good electrical insulating property  Because of all the above properties it is known as WONDER PLASTIC •…
