The purpose of this lab is to identify the physical and chemical properties of four liquids: acetone‚ vinegar‚ hydrogen peroxide‚ and oil. By using our knowledge about the four liquids we needed to identify the components of an unknown mixture. Theoretical Background The liquids commonly found around the house such as acetone‚ vinegar‚ hydrogen peroxide‚ and oil was tested to identify the physical and chemical properties of these liquids. Acetone usually used as nail polish remover dissolves plastic

In this lab‚ we were able to determine measuring the pH of liquids work. We were able to compare the liquids based on their pH level and determine which liquid was acidic or basic. Our results showed that if something came out to be seven or less‚ according to the pH scale‚ it means that an acid is a substance that donates hydrogen ions. Because of this‚ when an acid is dissolved in water‚ the balance between hydrogen ions and hydroxide ions is shifted. Now there are more hydrogen ions than hydroxide

Title: Liquid Chromatography Author: Gloria Contreras Lab Partner: Jose Montanez Instructor: Teresa Potter Date Work Performed: January 13‚ 2015 Date Submitted: January 20‚ 2015 Abstract: In this lab‚ liquid chromatography is used to separate the Red 40 and Blue 1 dyes inside of grape flavored Kool-Aid. It was determined that the 5% isopropanol will remove the Red 40 dye from the stationary phase. The 28% isopropanol will remove the Blue 1 dye from the stationary phase. The more

2:05 P.M. Purpose: The purpose of the experiment is to measure the densities of liquids. Specifically‚ the two liquids that were used and measured in the research were deionized water (H2O) and alcohol (C2H5OH). Methods: Density is an intensive quantity that cannot be visually identified. Therefore‚ the most straightforward approach to this problem was to record the measurements of mass and volume. For volume of each liquid‚ the instruments used were a 50ml burette‚ a 50ml graduated cylinder and a 10ml

Surface Tension Properties of Liquids Introduction The purpose of this experiment is to measure and record the surface tension of water and other aqueous solutions using capillary rise method techniques and practicing lab safety. In this laboratory the surface tension of water depends on the concentration of the following solutes; NaCl‚ acetone‚ and sodium dodecyl sulfate (SDS). Intermolecular interactions as well as other phases (solid‚ or air) make a liquid exist. The data collected will show

DENSITY OF LIQUIDS PREPARED BY BURAK COBAN PURPOSE: In this experiment we will learn how can we find the density of liquids and liquids of density how change effect of temperature‚ pressure‚ mass‚ volume and concentration. For this reason we will take NaCI solutions with different concentrations and we will measure their densities‚ so we will find out the effects of concentration on density of solutions. THEORY: Density is a physical property obtained by

consistency and above a liquid consistency. Therefore‚ the soil has two important properties to be analyzed‚ the Liquid Limit (LL) and the Plastic Limit (PL). The Liquid Limit is the moisture content that makes the soil has a liquid behavior. The Plastic Limit is the moisture content below which the soil becomes from the plastic state to the semi-solid state‚ which means it loses the ability to be shaped and starts to become brittle. 1.2) Purpose of Experiment To determine the Liquid Limit‚ Plastic Limit

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 hot-plate

Properties of Gases CHE101 Experiment date: 06/20 Write-up date: 06/21-06/22 Purpose: The purpose of this experiment is to examine different properties of gases in order to be able to identify them in a laboratory setting. I will be using Hydrochloric acid‚ mossy zinc‚ Bromothymol blue‚ limewater‚ Manganese‚ and Alka Seltzer‚ to test different properties of gases formed by chemical reactions. In order to extract the gas I will use several household products such as vinegar‚ baking soda‚ water
