Gravimetric Determination Of Soda Ash – Lab Report

By: Hector Manuel Gonzalez Avalo, lab partner; Benjamin Horrocks Introduction:  Soda Ash (Na2CO3, sodium carbonate) is commonly assayed and reported as its Na2O content. Soda ash is used mainly in glassmaking, where it supplies sodium oxide (Na2O) to the melt. Among other applications of soda ash is its application in “water glass”, a raw material that contains sodium oxide. Water glass is used as a source of sodium for several industrial products, such as; laundry detergents, binders and adhesives. As a […]

The Synthesis and Gravimetric Analysis of Alum

The Synthesis and Gravimetric Analysis of Alum By: Omish Samaroo Introduction  The purpose of this experiment is to synthesize the double salt alum, which has the formula KAl(SO4)2•nH2O, where n is the number of waters of crystallization that are incorporated into its crystalline structure. By determining the percent of water by mass in the compound through gravimetric analysis, the value of n in the empirical formula of alum can be determined.  The presence of potassium, aluminum, and sulfate is determined […]
