Alkali

The purpose of this lab was to analyze and examine periodic trends of the first 36 elements that are on the periodic table. Trends that were analyzed and examined are the atomic radius (AR) and the first ionization energy (IE) of the 36 elements. The hypothesis for this lab was that the elements that are in the groups that had the highest atomic radius would be in the same groups as those who have the the highest first ionization energy and the groups who have the lowest atomic radius would be…

This is achieved through the existence of the equilibrium HA (aq) ⇄ H+ (aq) + A- (aq). When a strong acid or alkali is added the equilibrium shifts to the right or the left adhering to Le Châtelier 's principle, which states that whenever an equilibrium is subject to change of concentration, temperature, volume, or pressure, the system will readjust itself to some…

In this study, the changes in the rheological curves of polyvinyl chloride (PVC) plastisols with increasing storage time and the factors affecting the changes were studied,. The results show that with increasing storage time, all the "viscosity–temperature" and "viscosity–time" rheological curves of PVC plastisols exhibit non-normal distribution change trends, i.e., the viscosity first decreases, and then changes from slow increasing to rapid increasing, forming a shoulder peak, reaches to the…

yet strong material called “Gorilla Glass”. When “compared to other brands of glass Corning’s Gorilla Glass is particularly: hard, thin, lightweight, and scratch resistant.” According to Anne Marie Helmenstine, “The glass consists of a thin sheet of alkali-aluminosilicate.” The glass is then “strengthened using an ion-exchange process which forces large ions into the spaces between molecules on the glass surface.” The process in which Gorilla Glass is made isn’t quite complex, according to…

is a very acidic substance that causes obvious damage to tissue and metal. Corrosives act directly by chemically destroying the part (oxidation), or indirectly by causing inflammation. Acids and bases are common corrosive materials. Concentrated alkalis are also very corrosive. They attack metals and skin if used in the wrong ways or spilled. They are just as dangerous as highly concentrated…

Gibson 1 Reagan Gibson Tripp Sanders Chemistry 1 May 2016 Introduction A Chemy Called Al is quite an interesting read. It is written by Wendy Isbell. It tells the story of a girl named Julie. The book begins talking about Julie and her electrical issues. It talks about her power being out but the TV still being on. It had to do with X-Ray Machines around the whole country. Well she goes to the land of Mathematics, she is afraid her friends are in danger- so she decides to go find them.…

IV. METHODOLOGY SAPONIFICATION VALUE Saponification is a method used in treating a neutral fat with alkali, breaking it down to glycerol and fatty acids. The saponification value or saponification number is the amount of alkali needed to saponify the given quantity of fat or oil, expressed as mg potassium hydroxide to saponify 1 g of the sample. In this experiment, the researchers used chemicals such as ethanol, hydrochloric acid (HCl), potassium hydroxide (KOH) and phenolphthalein indicator.…

these plants and it has been associated with economic condition in certain parts of the World; especially the tropics and sub tropics." These plants are called cyanophoric plants because they contain phytotoxins. Cyanide is very highly reaction to alkali earth metal. They mostly reactive to salt such as potassium, sodium, and calcium but are less reactive to copper, cadmiun, and molybdenum. In these studies, Ogundele and Caxton Martins are taking the metabolism of glucose up by neuron,…

This discovery took place in England; the year of 1807. It was founded from the english word “potash” and the arabic word “qali.” The word “qali” means alkali which is potassium's family on the periodic table. Potassium then was recognized as an element when potassium carbonate was mixed with animal fat to make soap. Therefore, it was made by extracting wood ash with water. The name “potash” was derived…

An estuary is a body of water in which fresh water from streams and rivers flows into seawater-containing oceans (Estuaries, 2008). The mixture of both seawater and fresh water is termed brackish water (Estuaries, 2008). Salinity depends on the exact location of an estuary, as the salt concentration is nonexistent in the fresh water end compared to the sea water end. The normal levels of salinity are between 0.5 to 35 ppt (Estuaries, 2008). Based on the central location of the fish kill site…
