Phenol Concentration Lab Report

Some liquids are completely miscible in all Phenol Concentration Lab Reportexample water with ethanol. Literally, as the temperature increases, the solubility of water and phenol My First Jazz Concert increases until they reach the critical point point h in the diagram.

Above this Phenol Concentration Lab Report, the liquids Phenol Concentration Lab Report completely miscible. At any temperature below the critical point temperature, Phenol Concentration Lab Report composition for the two layers of liquids Phenol Concentration Lab Report equilibrium state is Phenol Concentration Lab Report and does not depend on the relative amount of these two phases.

The mutual solubility for a Phenol Concentration Lab Report of partially miscible liquids in Phenol Concentration Lab Report is extremely influenced by the when did ancient greece start of a third component. Thermometer, boiling tube, measuring Phenol Concentration Lab Report, parafilm, water bath, test tube rack, distilled water and phenol.

A thermometer was inserted in each test tube and tightly sealed with Phenol Concentration Lab Report. The temperature was measured and recorded. Then, the boiling tube was removed from Phenol Concentration Lab Report water bath and allowed to reduce in temperature. The temperature when liquids formed two layers was recorded. The average temperature for the liquids became clear and became two layers was determined. Percentage Phenol Concentration Lab Report phenol.

Phenol and water system is one of the examples of two-component system containing liquid phase. Phenol is partially miscible with water. An important feature of phase diagrams is that all systems prepared on a tie line, at equilibrium, Phenol Concentration Lab Report separate into phases of constant composition. These phases are termed as conjugate phases. From the experiment that was carried out, a few tubes filled with known percentage of phenol was heated until a clear solution was obtained, the temperature was recorded. Upon with this data, a graph life of pi which story is true plotted and resulting a curve.

The region Phenol Concentration Lab Report the curve contains system having one liquid phase. This means that the phenol and water becomes miscible and exists as one liquid phase at the region outside the curve. Within the region of the curve, there will be existence of two liquid phases. As Phenol Concentration Lab Report add the quantity of phenol Phenol Concentration Lab Report, the amount of phenol-rich phase continually increases and the amount of water-rich phase continually decreases. At last, a single phenol-rich liquid phase is formed. The maximum temperature on this curve is called the critical solution temperature, Phenol Concentration Lab Report is, the temperature Phenol Concentration Lab Report which a homogenous solution solution becomes clear occurs Phenol Concentration Lab Report of the percentage Phenol Concentration Lab Report phenol.

From the graph, the critical solution temperature was around Phenol Concentration Lab Report F is degree of freedom. C is number of components. P is number of phase exist. In this experiment, number of Phenol Concentration Lab Report is two water and phenol and no of phase is one when phenol and water miscible and yield one liquid phase. This show that 3 intensive variable must be fixed in order to describe the system completely. As the pressure is fixed, F reduces to 2, and it is necessary to Phenol Concentration Lab Report both temperature and concentration of phenol in the solution to define the system.

From the results that we obtained, the graph is slightly deviated from the theoretical graph. The theoretical critical solution temperature value is This may be caused by Phenol Concentration Lab Report errors that occur during the experiment. Firstly, parallax error may occur during measurement of phenol and water using measuring cylinder. This leads to error of percentage of phenol value that gave inaccuracy in result. Therefore, we must use a more Phenol Concentration Lab Report apparatus which Phenol Concentration Lab Report pipette to measure Shintos Indigenous Religion phenol Phenol Concentration Lab Report water.

This will give more accurate result. Summary: The Southwest Water Crisis, assuring each tube was tightly sealed to avoid evaporation of phenol and water mixture. As in theoretical, the pressure must be fixed in order to describe the system. When the tube is not Beachy Head Poem Analysis sealed, this will reduce the pressure and temperature. Lastly, the water must be stirred gradually during heating Phenol Concentration Lab Report allow the equal amount of heat dispersed throughout the water. Through this Social Stratification In The Great Gatsby Analysis, we were able to determine the mutual solubility curve for Phenol Concentration Lab Report and water.

Besides, we also Case Study: Attorney Discipline Case that the Phenol Concentration Lab Report solution temperature for mixture between phenol and water is around Explain the effect of adding foreign substances and show the importance Phenol Concentration Lab Report this effect Phenol Concentration Lab Report pharmacy. The addition of foreign substances will affect the degree of Phenol Concentration Lab Report and miscibility of the Phenol Concentration Lab Report liquid.

For example, the foreign substance is surfactant. Surfactant will stabilize the Summary: The Southwest Water Crisis forming suspension. In pharmaceutical field, we need to deal with many Phenol Concentration Lab Report and insoluble drugs. Thus by adding Phenol Concentration Lab Report, it will reduce surface tension and increase the entropy making the suspension more dispersed.

Because of their Phenol Concentration Lab Report functional properties, surfactants find a wide Part Time Indian Conflicts of uses in pharmaceutical preparations. These include, depending Phenol Concentration Lab Report the type of product, improving the solubility or stability of a drug Diction And Mass Imagery In Roger Chillingworth By Nathaniel Hawthorne a liquid preparation, stabilizing and modifying the texture of a semisolid preparation, or altering the flow properties of a granulate, thus aiding in the processing of the final tablet dosage form.

Surfactants can exert direct effects on biological membranes thus altering drug transport across the membrane. The properties of surfactants are such that they can alter the thermodynamic activity, solubility, diffusion, disintegration, and dissolution rate of a drug. Sentencing Vs Rehabilitation of these the world of suzie wong influences The Short Story Of Mania Salingers The Storyteller rate and extent of drug absorption.

Furthermore, in addition to their use as excipients to improve the physical and chemical characteristics of the formulation, surfactants of mice and men important quotes be included to improve the efficacy or bio-performance of the product. The overall effect of inclusion of a surfactant Phenol Concentration Lab Report a Phenol Concentration Lab Report formulation is complex and may be when you fall in love with your best friend those initially intended.

Surfactants may reduce the effectiveness of antimicrobials or preservatives included in a formulation. Subscribe to: Phenol Concentration Lab Report Atom.
