Laboratory #16: Analysis of Grease in Water by Solvent Extraction Experiment Date: 2/19/10 Due Date: 2/26/10 II. Objective The goal of this lab was to determine the amount of impurity‚ in the form of oil‚ in water using the method of solvent extraction‚ also known as liquid-liquid extraction‚ a method of separating two materials with different physical and/or chemical properties. Two methods of evaporation will be used to finally determine the concentration of impurity- one using an explosion-proof

In this lab‚ we will be analyzing alum by doing three different tests. The first will be to find the melting point‚ the second to find the amount of water in alum‚ and the third is to find the percent sulfate. We expect the values to be close to the actual.

Introduction In a scientific observation‚ measurements are necessary to collect data and to give the objects that we observe a quantitative identity. In order to make valid measurements‚ scientists strive to make their measurements both accurate and precise. Today‚ scientists use the metric system‚ which is the most widely used system of measurement. The purpose of today’s lab is to make metric measurements of length‚ mass‚ volume‚ and temperature. Summary of the Procedure Procedure 2.1

Basic Lab Measurements and Equipment Purpose This lab experiment displays the accuracy of scientific measuring equipment. This experiment also helps to familiarize the students with these instruments. Procedure: Measure Volumes and Masses 1. Obtain a 400mL beaker and record its mass in grams. 2. Add 40mL of water to the beaker and record the volume. 3. Records the beaker’s mass now with the added water 4. Transfer the water from the beaker to a 50mL graduated cylinder and record the measurement
Premium Test method Chemistry Volume
density is represented by the ratio of its mass and volume. It is given by the equation ρ= massvolume 1. The SI unit of density is kg/m3. However‚ its CGS units‚ g/cm3 or g/ mL‚ are the most commonly used ones in the laboratory. The conversion is given by 1 gcm3=1gmL=1000 kgm3 [1]. The density of a homogeneous liquid is also defined by the amount of mass per unit volume. Liquid is usually confined in a container‚ so its volume is relative to the volume of its container [2]. There are various
