ACID BASE TITRATION OBJECTIVES 1. To demonstrate the basic laboratory technique of titration 2. To learn to calculate molarity based on titrations INTRODUCTION Molarity (M) or molar concentration is a common unit for expressing the concentration of solutions. It is defined as the number of moles of solute per liter of solution (or millimoles of solute per milliliter of solution). The concentration of a basic solution can be determined by titrating it with a volume of a standard acid solution (of

Abstract There are many methods employed to precipitate proteins out of solution. In this experiment we manipulated many physical and chemical variables in order to achieve purification of a protein via precipitation. In the first part of the experiment we purified the protein casein by modifying it’s pH. In the second part of the experiment we manipulated the ionic strength of albumin in egg whites‚ in a process called salting out. By manipulating these chemical properties we were able to

Determination of presence of protein in a variety of food substances by the use of Biuret Reagent Biol. 1040 Section 1005 Introduction The human body consumes carbohydrates‚ lipids‚ and proteins each day by eating a variety of foods. These foods are required for energy and human growth. Proteins are a diverse group of macromolecules with many different functions (Mbuthia‚ 2012). Many are structural components of bone‚ muscle‚ hair‚ tissue‚ etc. Others are enzymes that speed up cellular

Protein SCI/241 Protein A protein are organic compounds that made up of amino acids and are the building blocks of the cells in the body. Every cell in the body requires proteins to grow and repair themselves so these proteins are necessary for a healthy body and survival. Having so much protein can hurt your body so when you consume so much can get you sick and the right size of protein can keep you from getting sick. They’re five types of protein in everything that we eat. The largest class

Lab2: Testing for Proteins and Starches In this lab 8 total substances were tested to find out whether they are a Protein or a Starch. It is my belief that only 1 or two of each of the substances in test 1( proteins) and test 2 (starch) will test positive for either protein or starch. For this lab the following materials were needed to complete the experiments in test 1 for proteins: Di water‚ ev milk‚ 50% egg solution‚ 1% sucrose‚ 4 test tubes‚ 1 test tube rate‚ safety glasses‚ pipets and
