Gravimetric Determination Of Soda Ash – Lab Report

By: Hector Manuel Gonzalez Avalo, lab partner; Benjamin Horrocks Introduction:  Soda Ash (Na2O sodium oxide) is derived from sodium carbonate. Sodium oxide is a salt used mostly for ceramics and crystal making. 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 chemist the determination of the amount of this […]

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 […]
