Alkali

High in the Sierra Nevada mountains, there is Mono Lake, which is a large but secluded lake tucked away in a depression in the ground a few miles away from the nearest road. At first glance, it may seem like just another normal lake, but it is home to a bizarre, otherworldly landscape that was created when water from fresh water springs underneath the lake mixed with the lake’s salty, alkaline water, forming deposits of limestone. Near the south shore of Mono Lake, grotesque towers of rough,…

Soap and Detergent Soap and Detergent are the cornerstones of human cleanliness. Soap is, “a substance used with water for washing and cleaning, made of a compound of natural oils or fats with sodium hydroxide or another strong alkali, and typically having perfume and coloring added”( Soap 2018 ). Detergent is, “ a water-soluble cleansing agent that combines with impurities and dirt to make them more soluble and differs from soap in not forming a scum with the salts in hard water” ( Detergent…

pollution of industry to natural disasters. Acid is a chemical substance that can subdue alkalis, can dissolve specific metals and can turn them into salt, such as calcium, turns red on blue litmus paper, is corrosive or sour-tasting when it comes to liquid, generates pain in wounds, and turns colorless when placed in phenolphthalein which is used as a basic to acid indicator ("Definition of acid in English:"). Alkalis is any kind of substance that can produce OH ions, hydroxide ions, in water,…

mineral petalite (Jefferson Lab Web). However, even though this element was found by Arfvedson, William Thomas Brande and Sir Humphrey Davy were the first people to isolate it (Jefferson Lab Web). Lithium is very abundant, it is a soft silver white alkali metal with the atomic number of three. Lithium is silver and contains no odor (Element Project). In addition to those features, lithium has a total of seven isotopes, two natural and five unnatural. The two natural occurring isotopes are…

In experiment 2, we observed that the reaction of halogenoalkanes with aqueous alkali and water which contains dissolved silver nitrate. Halogenoalkanes are alkanes which have one or more hydrogen atoms replaced by halogen atoms such as fluorine (F), chlorine (Cl), bromine (Br) and iodine (I) which are the elements in group 7 in periodic table. Halogenoalkanes have the general formula, RX, whereby R is an alkyl or substituted alkyl group and X is any of the halogen atom. Besides, halogenoalkanes…

presence of any peroxide 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…

neutral conditions, but this only allowed for detection of double stranded DNA breaks. In 1988 the technique was adapted to use alkaline conditions that made it more sensitive and allowed for analysis of double stranded and single stranded breaks and alkali-labile sites (apurinic and apyrimidinic). The most common use of this test is to analyze white blood cells or lymphocytes in human biomonitory studies, but comet assay can also be used in toxicology, pharmacy, genotoxicity, and genetic…

solution with the Na+ forming citric acid, which is a weaker acid than hydrochloric acid. There is also an excess amount of Sodium Bicarbonate present with solution and the bicarbonate ions act as the main buffering agents neutralising any acid or alkali added producing water. (UMN 2000); the NaHCO3 is an antacid, so also helps neutralise stomach acidity, relieving acid indigestion and heartburn.…

19 Nov. 2008. Television. This episode of Mythbusters shows how the different Alkali metals react with water. They explain how as you move down the group, the more unstable the elements are, making each one more reactive and sometimes explosive than the last. The hosts do experiments with Rubidium (Rb) and Caesium (Cs) and show its…

Ice cream is defined as a sweetened frozen food which is composed of dairy products like milk, cream and infused with sugar, stabilizers, emulsifiers, flavorings, water and air. Ice cream varies all over the world this is because the mixture of the ingredients is different from one another. But a good ice cream is composed of: 12% milk fat, 14% milk solid non-fat, 15% sugar, 0.2% stabilizer, 6.2% emulsifier, 55-64% water which is still exclusive of air. Since, ice cream is a whipped product; it…
