Experiment1Separation of mixtures by filtration and crystallisationBackgroundThe separation of a mixture of two solids can often be achieved by filtration and crystallisation. To be successful‚ this requires that the components of the mixture have different solubilities in a particular solvent. AimThe purpose of this experiment is to separate sodium chloride/charcoal and sodium chloride/copper(II) chloride mixtures.

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

important aspects of the U.S. foundation‚ the federalism and the constitution. The framers of the constitution knew that it will be important to divide the powers of the governmental power‚ because that way there will not be abuse of the power. Separation of powers imposes internal limits by dividing government against itself‚ giving different branches separate functions and forcing them to share power. Federalism is the system of government in which power is divided between a central government

Industrial Separation Research a) Identify a mixture that is separated industrially: Olive oil b) Identify which ‘sphere’ it is obtained from: Biosphere c) Identify the industrial separation processes used on this mixture: Crushing/grinding: The olive fruit is crushed and ground by a metal hammer in a mill to make a paste. Beating: The olive fruit paste is added to water is additionally beaten to extract more oil from the olive cells. Salt can be used to assist osmotic breakdown [of the cells]

Separation of the Components of Vodka using Fractional Distillation Fractional distillation‚ also known as rectification or fractionation‚ is common in industrial usage‚ not only for simple mixtures of two components (such as alcohol and water in fermentation products‚ or oxygen and nitrogen in liquid air) but also for highly complex mixtures such as those found in coal tar and petroleum. The purpose of fractional distillation is to separate a mixture of two miscible liquids (liquids that mix
