colored in solution‚ and most of their compounds are white. It is impossible therefore to use colors of solutions or precipitates to indicate which of these cations is present in solution. Instead‚ in this experiment‚ you will use differences in solubility to separate from each other. APPARATUS: Small test tubes‚ test tube rack‚ litmus paper‚ test-tube holders‚ hot plate‚ centrifuge‚ three beakers (250 mL or 400 mL)‚ distilled water bottle‚ glass rod‚ dropping pipette‚ vial containing unknown

A Comparison of Gravimetric Analysis and Volumetric Analysis To analysis the proportion of an element in a certain substance‚ the experiment could be done by gravimetric analysis and volumetric analysis‚ and these two methods of analysing could be occupied on several different purpose of experiments as well. In a specific experimental condition‚ there will be one method that is the most suitable to choose‚ and it is depending on the temperature‚ substance status‚ pressure and chemical properties

Introduction: Recrystallization is used for the purification of solid compounds. The recrystallization process relies on the fact that majority of compounds are more soluble in hot solvent than in cold. The hot saturated solution containing the compound will have unwanted impurities and will be filtered out and cooled to produce the pure crystal constituents of the compound. Thin layer chromatography can be used as a physical method to segregate compounds from natural sources. E.g. Spinach

Use of ScaleSoftPitzer to calculate deposition‚ or precipitation‚ in a reservoir or core material during long term flow. Approach will be presented in four steps: 1. Determine whether equilibrium‚ kinetics‚ or mass transport is controlling‚ 2. Relate precipitation to the physical variables in the field or laboratory core‚ 3. Relate the physical variables that affect scale formation or dissolution to space and time in the reservoir or core material‚ and 4. Combine the two into a single

chloride has one molecule of hydrogen and one molecule of chlorine: Hydrogen chloride has a very powerful smell. It is in the form of a gas but only when it is at room temperature which is approximately 25 Celsius and when the pressure is high. The solubility of hydrogen chloride is very high this means that it can dissolve in water quickly because it dissolves many times in its own solution (the gas form of hydrogen chloride). It is very soluble because the smaller the chain of the molecules are then

Alyssa Erika L Borras Date Due: 18 January 2013 Date Submitted: 18 January 2013 Experiment No. 3: GRAVIMETRIC DETERMINATION OF PHOSPHORUS IN FERTILIZER SAMPLES I. Abstract The purpose of this experiment is to determinethe Phophorus content of fertilizer samples using Gravimetric Analysis. It involves dissolution of the fertilizer sample‚ precipitation and heating and cooling of the sample. Pooled standard deviations

unknown sample in a test tube or spot plate‚ then add a few drops of 1M NaOH solution. At the same time suspend a piece of red litmus paper over unknown solution. If red litmus paper turns blue‚ it indicates the existence of NH4+ ion. 3.Sample solubility and solution tests (i) Dissolve ~1/2-2/3 of sample in ~10-15mL of DIW. Always retain a sample of original sample! This sample/DIW ratio will give ion concentrations of ~0.1-0.2M for soluble salts of unknowns. (ii) Observe pH to one SF

comes to comparing the mixture of water/pentane and the mixture of pentane/methanol. When food dye was added‚ it was able to form a homogeneous mixture of food because the food dye was a polar molecule‚ which made it water soluble. The next part of the lab was spent observing the effect chain length has on miscible alcohol in water. The result in table 4 matches the hypothesis that the longer hydrocarbon chain stays in a molecule‚ that molecule will become less polar. This hypothesis sort of made sense
