Alkali

suggests that it is highly reactive and use of water and any other chemicals that can lead to an undesired chemical reaction will be ruled out. Also, the spilled chemical is producing fumes, mostly it suggests that it is either a strong acid or an alkali in addition to its corrosive nature. Use of carbon dioxide to manage the fumes/vapors will also be ruled out as the carbon dioxide is likely to react with the chemical to form dangerous substance. Therefore, the choice left is a method which…

1. Furosemide (Loop-diuretics) Indication: Furosemide is a loop-diuretic that is indicated for use when treating Hypertension, Hyperkalemia, and edema that is from kidney failure, congestive heart failure, or liver cirrhosis. MOA: Its mechanism of action is to interfere with the chloride-binding cotransport system and inhibits the reabsorption of chloride and sodium ions at the distal and proximal tubules, and the loop of Henle. This leads to the pharmocological effects of enhancing the…

The world we live is a home to the splendid panorama of mountains, majestic volcanoes, marvelous rivers, and boundless deserts. Our delightful planet is a very compelling and captivating place but we should not forget how threatening Mother Earth can be. Traveling means unwinding, relaxing, and leaving all your worries behind. There are risks when travelling to any parts of the world but there are also places that are very dangerous especially to unaware travelers. Dangers come in different…

Chemical Industry is one of the oldest and largest industries in the world, forming the backbone for many other downstream industries. It produces products and materials, 70% of which forms the input for other industries like Agriculture, Automobile, plastic, textiles, petroleum refining, primary metal and chemical industry itself which consumes 26% of its own output. Rest of the production is consumed directly in form of detergent, soap, perfumes and other consumer goods. The global chemical…

can increase the corrosion rate of mild steel. At a ph of 3 the corrosion rate can increase tremendously. Metals having the potential to react to an acid or a base, known as amphoteric metals, in addition show an increase in the corrosion rate in alkali environments. Aluminum and lead are some examples of amphoteric…

Burns are one of the leading cause of medical emergencies in the United States. While young child typically under the age of five years old and adults over the age of sixty-five years old suffer with more burns than any other age group. Children and older adults have a harder time healing from serious burns due to the lack of hydration in the body and the skin is so fragile so burns tend to be deeper. Women usually only account for 31 percent of burn patients while men account for 69 percent.…

that such pigmentation may cause problems with intestinal absorption of nutrients.(6-7) Although the diagnosis of PDG is clear on endoscopy nevertheless differential diagnosis includes necrosis, metastatic melanoma, and ingestion of charcoal (8) and alkalis.(9) PGD is mostly asymptomatic but cases have been reported in the literature in which patients presented with dyspeptic symptoms. Histologically, pigments are deposited in the lysosomes of macrophages in the lamina propria(10). The…

By adding Hydrochloric acid into solid Magnesium, in Data table #2, when Hydrochloric acid was first been added to solid Magnesium, the ribbon immediately start to bubble and producing fumes at the same time with a burning sound. Magnesium start to turn into a white liquid form. After the bubble start to disappear, more Hydrochloric acid was added, and the reactions repeats. Until none of the shiny silver Magnesium ribbon can be seen, and there is no more bubble, the reaction is over. After…

Turbidity: - Turbidity is a degree of water clarity. Turbidity is defined as an “expression of the optical property that causes light to be scattered and absorbed rather than transmitted in straight lines through the sample”. Nephelometers are used to measure the intensity of light scattered by contaminants present in water such as suspended and colloidal solids like clay, silt and microscopic organisms. Turbidimeters using the principle of nephelometer compare the light scattered due to…

NaOH solution till PH 7.5 was attained (when the colour just started to turn pink). The following equation was applied to establish equivalent weight: Equivalent weight (EW)=(weight of pectin sample x 1000)/(volume of alakali (〖cm〗^3 )x Normality of Alkali) The…
