CHM1032L pre/post lab instructions Preparation is a key to success in this lab. For this reason‚ you are required to thoroughly read through the experiment information presented in the lab manual‚ and complete a pre-lab for each experiment you do. The prelab must be completed prior to the day of the experiment. Each Friday I will ask to see your completed prelab before I allow you to enter the lab. If you have not finished the pre-lab‚ I will not allow you to enter the lab and you will receive

16 Date Performed: July 10‚ 2013 Group No.: 4 Date Submitted: July 17‚ 2013 Experiment #1: Measurements INTRODUCTION Density is a physical property of matter‚ as each element and compound has a unique density associated with it. The unit of Density is g/cm3 or g/mL. It is used to measure thr relative “heaviness” of objects with a constant volume. As defined‚ the formula for Density is Mass over Volume (ρ=m/v) and it can be rearranged to get the Volume (v=m/ρ) or Mass (m=ρv) of a certain

part (i) (a)‚ the solid copper(II) nitrate is used to dissolve in a test tube filled with half distilled water. The solid copper(II) nitrate ionize in water to form copper(II) ions and nitrate ion. Hence‚ a blue solution is formed due to the blue copper(II) ion present in the solution. When excess solid is added‚ the solution will become saturated and do not allow any solid to dissolve‚ so excess solid will remain in the solution. This is shows that the equilibrium between solid and aqueous copper(II)

from a Solid Mixture by Liquid-Liquid Extraction Introduction Liquid-liquid extraction is a technique used to separate chemical substances in order to purify or identify the various components of a mixture. Flavors‚ spices‚ perfumes‚ and medicines are just some of the everyday things that are extracted from plants and other natural sources [1]. The basic principle used to carry out this separation is the mixing of two liquids that are immiscible with each other. This creates layers of liquid‚ which

Post-Lab Report for Experiment 2: Cooperative Identification of an organic Solid October 6‚ 2013 Introduction: This experiment was focused on the cooperative identification of organic compound by its chemical properties such as: slow melting point‚ mixed melting point‚ Rf values in TLC experiment‚ IR spectrum analysis‚ and H NMR spectra. Such data can provide the the identity of functional groups and the identity of the compound itself. In this experiment

10/1/13 Cubs Density The purpose of this experiment is to find out the density of the unknown solid object by determining the mass and the volume through the experiment. To do this we will be get the mass of the object and determine the volume of the object by placing it into a liquid. Then we will divide mass by volume and get its density.

Title: Lab #3 Separation of a Mixture of Solids Purpose: To understand the different separation methods and techniques that depend on the chemical properties of a specific substance. Also to become more comfortable with performing those actions of separation so I have them in the future. For this experiment‚ I will separate a mixture of four distinct substances: sodium chloride‚ benzoic acid‚ silicon dioxide‚ and iron fillings into pure beings. Procedure: Materials: distilled water coffee
