The Separation of a Liquid Mixture by Simple Distillation Objective The purpose of doing this experiment is to separate two miscible liquids samples of cyclohexane and toluene using simple distillation. The objectives will be to record boiling range and volumes (mL) of distillates that are attained during the process of distillation. Background Distillation is a frequently used technique for separating mixtures based on differences in the boiling points of components in the mixture. The

acid. Calcium carbonate is a chemical compound with the formula CaCO3. It is a common substance found in rocks in all parts of the world‚ and is the main component of shells of marine organisms‚ snails‚ coal balls‚ pearls‚ and eggshells. When these two reactants are combined results in the production of Calcium Chloride (CaC2)‚ Carbon Dioxide (Co2) and Water (H2O). Aim: To investigate the rate of reaction between Calcium Carbonate (CaCo3) and hydrochloric acid (HCl) by changing the molarity of the

With this lab I was able to determine and execute the proper separation of a mixture of solids through various means‚ such as evaporation and filtration. Using these techniques presented the separation of different ingredients from a mixture was conducted based upon the usage of individual physical properties of each substance presented in the mixture. . Observations: Throughout this experiment I noted several things

Separation of a Mixture Do-Your-Own-Lab What you will need to do: 1. Create a flow chart for the separation of your unknown mixture – BERFORE doing lab 2. Create data table – BEFORE doing lab 3. Do lab 4. Analyze data – calculate percent composition of your unknown mixture = 15 points = 30% 5. Write a complete lab report = 35 points = 70% 1. A flow chart is often used to illustrate the steps involved in the separation of a mixture. Flow charts are constructed BEFORE

Nupoor Matieda October 10‚ 2014 PD 9/10 Lab Report Separation of a Mixture of Sand and Salt Goal(s): To separate a mixture of sand and salt and to find the percent of each component by mass of each mixture Background Theory: A mixture is a combination of two or more pure substances in which each pure substance retains its individual chemical properties. Mixtures can be separated by physical processes such as filtration and evaporation. Filtration is a process where solids

concentrations in the atmosphere‚ and thus the ocean‚ will continue to decrease the CO32- concentrations in the ocean and thus lowering CaCO3 saturation levels. In regions where the saturation state of aragonite or calcite is greater than 1‚ the formation of shells and or skeletons is favored whereas for values less than 1.0‚ the seawater is corrosive to CaCO3 (John M. Pandolfi). This corrosive condition results in dissolution. Dissolution of the carbonate minerals calcite‚ aragonite‚ and high-Mg

Copper (II) Sulfate Purpose: The purpose of this lab is to find out how many moles of water there are in one mole of Copper Sulfate (CuSO x HO) and the percent by mass of water in the hydrate. This will be accomplished by heating a determined mass of the hydrate to remove the water‚ and by measuring the salt left over. Introduction: This laboratory experiment will be done to find out how many moles of HO are present per one mole in the hydrate CuSO. A hydrate is a compound that has a fixed number
