Introduction:
Potassium aluminium sulphate, too known as Alum, is a salt entrap in many commercially made products. Alum is an component part in commercially made baking powderise, and gives baking powder the faint metallic taste. Alum is also used in the production of cucumbers, pickles, and maraschino cherries. The aluminium ions give the fruit a crisp taste because it strengthens the cell walls (2). Potassium aluminum sulphate is also used in some commercially produced and exchange deodorants (3). The Alum dodecahydrate is commonly used medicinally. The hydrate is found in several vaccines such as hepatitis a and hepatitis b. It can also be used to shrink hemorrhoids as well as stop the bleeding (4). In this lab we synthesized and analyzed atomic number 19 aluminum sulfate (KAl(SO4)12H2O) using a multiple diametric tests. These test included flame test, melting point, potassium test, sulfate test, and aluminum test. We also determined the number of waters of hydration in Alum. Experimentally and empirically potassium aluminum sulfate is a dodecahydrate (4). The purpose of the laboratory is to determine the number of waters of hydration in aluminum potassium sulfate as well as the purity of the Alum we produce.
Experimental1:
The procedure for this laboratory was followed closely from prof Abrams lab manual. In Part 1 of this laboratory an aluminum soda can was cut apart and the paint and decorate was rubbed off with steel wool. Next, the aluminum can was rinsed off with intercept H2O and then cut into small pieces. Using the uninflected balance 1.0537 g of the aluminum can was weighed out.
The 1.0537 g of aluminum was added to 40 mL of 1.5 M KOH(aq) in a 250 mL breaker. The slurry of KOH and Aluminum was then placed on a calefactive plate for 30 minutes. A filtration apparatus made with ergocalciferol mL Bucher stress flask, funnel and adapter was clamped to a stand. The filter paper was dampened with distilled water and placed it into the...If you want to get a full essay, order it on our website: Ordercustompaper.com
