INTRODUCTION 1.1 General Foundry sand is high quality silica sand with uniform physical characteristics. It is a byproduct of ferrous and nonferrous metal casting industries‚ where sand has been used for centuries as a molding material because of its thermal conductivity. It is a byproduct from the production of both ferrous and nonferrous metal castings. The physical and chemical characteristics of foundry sand will depend in great part on the type of casting process

Samantha Smith Organic Chem 255 Lab M/W 12:30-4:30 Hyejin Cho 12 June 2013 Separation of a Mixture Abstract: In this experiment‚ the three processes of extraction‚ sublimation and recrystallization will be used to separate a mixture of salicylic acid and naphthalene. The first part of extraction will be to separate the salicylic acid from the naphthalene using diethyl ether and aqueous sodium bicarbonate. The naphthalene will reside in the ether and be the top layer‚ while the

The Separation of Mixtures This lab demonstrates the difficult task of separating mixtures using different types of methods. This study is performed because it helps you understand the concept of separation and certain characteristics of elements. Previous knowledge in which already exists in this lab would be the process of filtration‚ distillation‚ magnetism‚ and evaporation. The specific hypotheses of this experiment was that the iron would separate through magnetism‚ the salt would separate
