AgCl to form instead of the desired solid PbCl2. The mixture was then centrifuged in order to let the solid particles of the three ions to fall to the bottom. Another drop of HCl was added to test if the reaction had been completed. If the solution were to turn milky white again then it would’ve signaled an incomplete reaction between the cations and HCl. The next objective was to separate the lead(II) ion from the mixture. The test tube with all three solids precipitated at the bottom was heated

Calculating the Density of Liquids II. Purpose/Background: The purpose if this lab was to determine the density of water and an unknown liquid. Density is defined as the mass of a substance divided by its volume. It is an intrinsive property of matter and is used to specifically characterize substances. III. Procedure: 1.We massed an empty 10mL graduated cylinder to the nearest .01g. 2.Then‚ we filled the graduated cylinder with 4.0-5.0 mL of distilled water‚ 3.massed it to the nearest 0.1

Lab Report 3 In this lab‚ we will take a trip to the planetarium lab and will learn about Right ascension and declination‚ and altitude and zenith. After looking at the different points shown‚ we will log the altitude and zenith in the chart in our lab manual. Now we will look at the same points and label the right ascension and declination. Then we will learn about the easiest way to locate the star Polaris. As we started the first program‚ we answered a few questions to make sure we knew

This lab report will be detailing the steps taken and the results discovered when using spectrophotometry to determine the percentage of copper in a copper-clad penny and the thicknes of the copper layer on the copper-clad penny. After 1982‚ copper coating has been used in the creation of the penny because the cost of pure copper has increase to the point that the amount needed t omake a penny cost far more than the actual value of the penny. This lab allowed us to see just how much copper coating

Objective: The objective of this lab was to find and examine the viscosities of ideal and non-ideal solutions. The ideal being the toluene/p-xylene and the non-ideal being the methanol/water. The second objective of this lab was to investigate the temperature dependence of viscosity (Halpern‚ 17-1). Introduction: Viscosity is the resistance to flow of a certain fluid. In this experiment two solutions are used. According to the definition of viscosity mobile liquids have a relatively low viscosity

:_________________ Date Submitted:__________________ Experiment # 2 Density INTRODUCTION: The density of a substance is physical property that requires measurements of mass and volume. The ratio of the mass per unit volume is density‚ d and is written as (D = m/v). Using the metric system‚ the ratio for solids and liquids is expressed in g/mL or g/cm. Matter expands and contracts according to temperature. For liquids and solids‚ the change in volume is very small‚ but for gases‚ a temperature
