Introduction to preparing standardized solutions and making dilutions Introduction: A solution is a mixture of the critical thinking company west buckland school two or more substances uniformly dispersed through a single phase, so that the mixture has the same composition throughout. A solution may be a solid dissolved in a liquid. A solution is comprised of a solvent and a solute, where: the buisness articles European University Cyprus, solvent is the liquid in which the solid dissolves (Water is the most common liquid solvent), the solute is the solid that dissolves in the solvent. In the example of the salt solution given above ( sodium chloride is the solute) A solution of buisness articles European University Cyprus known concentration is called a standard solution . Its concentration is determined by a process known as standardization. When making up a standard solution it is significant that the accurate mass of substance is exactly measured. It is also important that all of this is effectively transferred to the volumetric flask used to make up the buisness articles European University Cyprus, level. Preparation of standard solution by using standard substances in one of several ways. A primary standard is a substance of known high purity which may be dissolved in a known volume of solvent to give a primary standard solution . If stoichiometry is how to write an essay about my family pomfret school, used to buisness articles European University Cyprus establish the strength of a titrant, it is called a secondary standard solution . buisness articles European University Cyprus! The term secondary standard can also be applied to a. . Freezing Point Depression in Solutions The freezing point of pure water is 0°C, but that melting point can be depressed by the adding of a solvent such as a salt. The use of ordinary salt (sodium chloride, NaCl) on icy roads in the winter helps to melt the ice from the roads by lowering the melting point of need help writing essay the university of birmingham the ice. A solution typically has a measurably lower melting point than the pure solvent. buisness articles European University Cyprus! The following figures were found in a published report, but have not been checked out in detail. A 10% salt solution was said to buisness articles European University Cyprus lower the melting point to -6°C (20°F) and a 20% salt solution was said to lower it to -16°C (2°F). A more formal treatment of writing journal paper ashville college freezing point depression is buisness articles European University Cyprus, given by Ebbing. buisness articles European University Cyprus! The freezing point depression ΔTf is a colligative property of the solution , and for writing journal paper ashville college, dilute solutions is found to be proportional to the molal concentration cm of the solution : ΔTf = Kfcm Where Kf is called the freezing-point-depression constant. A pleasant application of how to write an essay about my family pomfret school the freezing point depression is in the making of homemade ice cream. The ice cream mix is put into a metal container which is surrounded by crushed ice. Then salt is put on the ice to lower its melting point. Need help writing essay The University of Birmingham! The melting of the solution tends to lower the equilibrium temperature of the ice/water solution to the buisness articles European University Cyprus, melting point of the solution . This gives a temperature. . determine the unknown concentration of potassium permanganate (KMnO4) solution by finding its absorbance through the use of spectrophotometer. The preparation of buisness articles European University Cyprus four known concentration of KMnO4 was done namely, 2.00×10-4M, 1.50×10-4M, 1.00×10-4M, 5.00×10-5M, respectively and is to be place on the spectrophotometer with the unknown and distilled water for the determination of each concentration’s absorbance. As the concentration is proportional with the absorbance of the solution , to determine the concentration of the solution is possible by drawing a graph of concentration against the absorbance. At the end of persausive essay queen margaret's school the experiment, the group found the concentration of the unknown sample is 2.50×10-4M. I. Introduction Spectrophotometry is a method to measure how much a chemical substance absorbs light by measuring the intensity of light as a beam of light passes through sample solution . The basic principle is that each compound absorbs or transmits light over a certain range of wavelength. buisness articles European University Cyprus! This measurement can also be used to measure the amount of a known chemical substance. Spectrophotometry is articles for persuasive writing the fessenden school, one of the most useful methods of quantitative analysis in various fields such as chemistry, physics, biochemistry, material and chemical engineering and clinical applications. A spectrophotometer is an instrument that measures the amount of photons (the intensity of light) absorbed after it passes through sample. .

Mixtures and Solutions can often become confusing because solutions are mixtures, but not all mixtures are solutions . Knowledge essay writing Wrekin College! A mixture can either be homogeneous or heterogeneous. A homogeneous mixture is where the mixture’s components are distributed uniformly within the mixture. A heterogeneous mixture is the critical thinking company west buckland school, where the components are not uniform. Mixtures can either be miscible or immiscible, the difference being whether or not the mixture forms a homogeneous mixture or not. In a solution a solute is soluble in a solvent. In a mixture the solute may be completely insoluble to the solvent. A heterogeneous mixture that would be Solid/Liquid would be Skim milk. Although skim milk contains mostly water it also contains casein, which is a small protein. The casein protein is buisness articles European University Cyprus, so small it may not be thought to the critical thinking company west buckland school be a heterogeneous mixture, but if the skim milk curdles the mixture can be separated. A Solid/Liquid solution could be Seawater. The seawater is homogeneous which makes it a solution . Persausive essay Queen Margaret's School!
