calculations. Analysis/ Critical Thinking Questions: Compare your data for the pure substances with the data for each of the two solid mixtures. Which of the pure substances shows behavior that is similar to what you saw with the the two-solid mixtures (Mixture 1 and Mixture 2)? If you cannot positively identify your mixture‚ discuss the possibilities for the mixture. The starch and mixture 2 are both similar because they both did not penetrate when the vinegar was added; when the water was added the laid on

Lab report on separation of mixtures Purpose- The purpose of this lab is to separate or isolate the desired product from large amounts of solvent and by-products. It is also followed by a purification step that removes trace amounts of other substances from the final product. One of the experimental techniques that we used in the lab to separate or purify mixture is fractional crystallization. In the experiment we used fractional crystallization to resolve a mixture of salicylic acid and CUSO₄ .5H₂O

Experiment 1: Viscosity of Liquids Victoria Kulczak Lab Partners: Laina Maines & Heidi Osterman Date of Lab: 2/21/11 Due Date: 2/28/11 Abstract: The goal of this experiment was to determine the viscosity of given liquids. Two different methods were employed‚ the first measures time of flow of several methanol-water solutions‚ from point A to point B. The second method involves dropping a foreign object‚ in this case a sphere‚ into a cylinder of glycerol and measuring the time it takes for it to

FE 106 GENERAL CHEMISTRY EXPERIMENT-1 DENSITY OF LIQUIDS PREPARED BY BURAK COBAN PURPOSE: In this experiment we will learn how can we find the density of liquids and liquids of density how change effect of temperature‚ pressure‚ mass‚ volume and concentration. For this reason we will take NaCI solutions with different concentrations and we will measure their densities‚ so we will find out the effects of concentration on density of solutions. THEORY:

43. Tobacco 3 Tobacco e-Liquids are the best in class‚ which are reproductions of the rich flavours of tobacco found in cigars‚ pipes‚ and cigarettes. If you want to enjoy a rich and smoky blow out‚ this is the E-Liquid for you. Like all e-Liquids‚ Tobacco E-Liquids use a proportion of PG and VG for the base and use a special blend of flavouring to get the tobacco taste. If you want you can as well add Nicotine into the e-Liquids at an altering level. 44. Tobacco 4 There are a large variety of

Liquid Crystal Display A liquid crystal display (LCD) is a flat panel display‚ electronic visual display‚ or video display that uses the light modulating properties of liquid crystals. Liquid crystals do not emit light directly. LCDs are available to display arbitrary images (as in a general-purpose computer display) or fixed images which can be displayed or hidden‚ such as preset words‚ digits‚ and 7-segment displays as in a digital clock. They use the same basic technology‚ except that arbitrary

Extraction Separation of a Carboxylic Acid‚ a Phenol‚ and a Neutral Substance Purpose The objective of the experiment is to identify the three substances in the mixture and to determine the percent recovery of each from the mixture. The unknown will consist of either benzoic acid or 2-chlorobenzoic acid‚ 4-t-butyl phenol. Determine the weight of crystals and also the percent yield Introduction There are various techniques of extractions‚ solid/liquid extraction‚ which

Determination of Cleansing Action of Detergents (Using Capillary rise) Synopsis This project report explains about the surface tension and capillarity of liquid through a simple experiment of finding the capillarity of various detergents. Oil stains and grease on dirty clothes cannot be removed‚ using water alone‚ because water does not wet them. If detergents added ‚ surface tension is decreased‚ the area of contact is increased

1.0 Summary This experiment is conducted to determine the liquid permeability of porous media. The apparatus used in the experiment is the liquid permeameter. The liquid used in this experiment is water. Three membrane samples of different thickness (0.1‚ 0.2‚ 0.3 cm) are used as the porous media. The determination of the permeability is carried out using elevated pressure test. Each sample is tested for 5 times at different values of pressure gradient which are 5‚ 10‚ 15‚ 20 and 30 psi.

Abstract The experiment allowed students to explore different electrolytes and classify them into acids‚ bases and salts by using different indicators or by measuring the pH levels of each. The experiment also helped students classify different substances through their conductivity properties. The preparation of a 1 M stock solution from NaOH pellets diluted to a
