Separation of Mixtures: Solids Essay

Aim The objective of this experiment was to separate a mixture of two compounds (ferrocene and acetylferrocene) using adsorption column chromatography. Introduction Adsorption column chromatography is a technique that uses a solid stationary phase which is fixed and a liquid mobile phase that moves slowly through the packed column. This technique uses the property of polarity as the compounds have a greater affinity towards the respective phases (either stationary or mobile) which leads the compounds

This video discusses 3 different types of chromatography. List each one mentioned, and describe their differences in as much detail

Objective: 1. To recover benzoic acid and p-dichlorobenzene from its mixture using acid-alkaline extraction. 2. To determine the percentage recovery and melting point of benzoic acid and p-diclorobenzene. Apparatus:Separatory funnel(250mL),Buchner funnel,beaker. Materials:Benzoic acid,p-dichlorobenzene,ether,10% NaOH,conc.HCl,distilled water, anhydrous CaCl2. Introduction: Organic compounds in an aqueous mixture can be separated by shaking the aqueous solution with a solvent which

of using different separation techniques on the substance extracted and the amount extracted. Research question: What is the effect of using different separation techniques such as magnetism, filtration and dissolving and evaporation on the substance extracted and the amount extracted. Background research: Salt - NaCl The name for table salt is, sodium chloride. It is an ionic compound with the ions bonded in the form of a giant lattice. As it is ionic, it is a mixture of a metal with a non-metal

significantly lower. From the melting points we can determine that unknown # 3’s melting point is closest to that of 2 – Octanone with an 8.6% error. This can be attributed by either the unknown being diluted with too much ethanol and water or the mixture containing traces of acid. However, as aforementioned, traces of acid would only lower the melting point not raise it, therefore it is unlikely that traces of acid can be attributed to the error.[3] From the H NMR spectrum, integration suggests that

The mobile phase the slowly rises up the TLC plate by the capillary action. Whilst the solvent is pasted the spot that was applied, a balance is then recognised between the components of mixtures as the molecules of a component which is then adsorbed on the solid and the molecules which are in a solution. However, the components within the solubility will then differ and the strength of their adsorption to the adsorbent and some components will then be carried upwards on

preparing the column chromatography set up, the column was plugged with cotton and uniformly packed with silica gel up to the intended part of the dropping pipette. 0.5 mL of the extract was then placed on top of the column using a pipette. The pigment mixture was eluted using 10 mL of DCM-hexane (1:1) and afterwards introduced in portions. The members were instructed not to allow the column to run dry. The colorless eluates were discarded while the colored eluates were collected in separate test tubes

consists of a “technique used to separate components within a mixture by allowing the pigments within the mixture to flow down the column that is filled with starch, alumina, and or silica.” The different bands would then appear as a result. Although not every time will the colors appear, there are different techniques for identifying them through chromatography. When reacted with different subjects or by means of physical separation. Chromatography works through a system of “partitioning compounds

Water treatment is a process essential to our infrastructure and the reusability of water, and electrostatics is at the heart of the interaction necessary for the operation to proceed. The general treatment process is comprised of about 6 steps: pre-treatment, coagulation, flocculation, sedimentation, filtration, and disinfection. Each one serves a specific purpose to the overall clarification of the raw water, but coagulation and flocculation are the most broad in the removal of contaminants in

useful separation technique in organic chemistry. This separation method involves the same principles as thin layer chromatography but can be applied to separate larger quantities than TLC. Column chromatography can be used on both a large and small scale. The applications of this technique are wide reaching and cross many disciplines including biology, biochemistry, microbiology, and medicine. The technique of TLC is useful in determining the type and number of ingredients in the mixture, but column
