One student in particular‚ given the table that the professor had given them as a guideline‚ decided that he would first mix the given mixtures with potassium sulfate‚ potassium carbonate and potassium phosphate in that exact order while centrifuging the formed solutions in between mixing. If the mixture‚ when reacted with potassium sulfate‚ forms a precipitate‚ it would be confirmed to have strontium ions‚ which were just separated from the mixture after centrifugation. The ions formed are certainly

Executive Summary Caffeine is a stimulant for the central nervous system which will relax the muscle and increase the gastric acid and heart rate (Kelly‚ 2017). The analyzing of caffeine and caffeine metabolites in saliva is to quantitatively measure the ratio of concentrations of caffeine and metabolites. There are three different metabolites of caffeine and the majority of caffeine metabolite is paraxanthine. The ratio of concentration represents the activity of the first metabolism enzyme of caffeine

Determination of Cations and Anions through Elimination and Confirmation Tests By: Symantha Resendiz Introduction A topic of great importance to all scientists is the identification of compounds‚ which is relevant in all aspects of their work in some way shape or form. Weather it may be determining what is causing sickness or what is polluting the air‚ it is very prevalent in the science world. In project 2‚ identification of cations and anions was preformed through a series of confirmation

Introduction • The problem we are studying was to determine the cellular damage of various concentrations of propanol‚ ethanol‚ methanol‚ NaCL‚ and sodium dodecyl sulfate henceforth known as SDS on Beta vulgaris to ultimately distinguish the ability of each solution to permeate the membrane of the Beta vulgaris. • Beta vulgaris contains a beta cyanin which is a water-soluble red-pigment‚ which remains in a healthy vacuole surrounded by the tonoplast membrane. When we damage the tonoplast membrane

Procedure: 1. Iron (IIII) and copper (II) sulfate solution. Fill a small test tube halfway with copper (II) sulfate solution. Add a 2.0 gram iron rod to the solution and observe the reaction. Observations: When I put the Iron (lll) and cooper (ll) in the test tube I notice that the color change to a darker gray at the beginning. Regarding to the sulfate solution I also notice that its color change in to a clear blue. When they are mixt together the blue solution vanished slowly while its color

Robert Lawrence and Edmund Stephens‚ two graduate students of geology from Columbia University‚ organized the Saline Salt Company in 1974. Keeping in mind the fact that every 1‚000 grams of seawater contains approximately 35 grams of various salts‚ the two men pictured limitless wealth for themselves by extracting these salts. Common table salt comprises 27 grams out of each 35 grams and is easy to extract; so‚ the men decided to begin producing it. They picked New Iberia‚ Louisiana as the ideal

extraction of Albumin from egg and the determination of protein concentration via the Warburg-Christian method and Bradford Assay method. In the first part‚ egg white underwent the addition of a weak acid‚ disruption of cell membrane‚ addition of ammonium sulfate and centrifugation. The product obtained was not weighed because of its relatively small amount and was considered a failure by the experimenters. In the second part of the experiment‚ the protein concentration of the product acquired from the first

! Isolation of the Components of BC Powder Introduction Aspirin‚ Caffeine and Salicylamide were extracted from an over-the-counter pain reliever (BC Powder). These components were separated by manipulating their solubilities by adjusting the acidity and basicity of the solution. By doing this‚ the three components were forced into conjugate acid (or base) forms‚ causing selective solubility in either an aqueous or organic solvent. These layers were then separated by use of a separation funnel
