Truc-Nhi Do Separation of a Mixture The purpose of this lab was to separate a mixture, calculate the percent composition by mass, and find percent error. I first started out by taking the mass of each component of the lab. I used the infiltration method to allow the salt and water solution, a blended mixture, to pass through the filtration paper and into the beaker. A trick to know if something is a solution is to see is it has the aqueous sign (aq) in the formula, like NaCl(aq). This step…

measured. 1 gm leaf sample was taken and chlorophyll a+b, carotenoids were measured (Aron, 1949). For biochemical analysis, 1 gm ground leaf sample was homogenized in 2 ml of 0.1 M ice cooled phosphate buffer containing 0.1 mM ethylenediamine tetra acetic acid and 1% (w/v) polyvinylpyrrolidone and inoculated 30 min in ice. This homogenate sample was centrifuged at 10000 rpm for 30 min at 4ºC and supernatant collected. The supernatant was assayed for Catalase (CAT), Superoxide dismutase (SOD),…

Slime was first created in 1976 by mattel ( A toy company) it was sold in little green trash cans. It was not stretchy or soft it didn't settle, or react to touch. The original slime was not made with pva or borate it was made with guar gum and didn't have an appealing texture. Slime is now sold across the world in shops online the main seller is Etsy but other slime sellers branch out and create their own websites. Like for example GlitterSlimes (Nicolette) started on Etsy and made her own…

8 Indian kitchen ingredients that are of great help in treating Mouth ulcers!! Mouth ulcers, also called Aphthous ulcers, are sores appearing in the mouth, mostly inside of the cheeks, that can be quite painful while drinking, eating, or brushing teeth. Mostly mouth ulcers are harmless and clear up on their own but if these sores persist more than 3 weeks, medical advice is necessary. The exact cause of mouth ulcers is unknown and is mostly varies from case-to-case. However, still there are many…

It does so via the use of two-component systems, one of which is called PhoPR two-component system6. In order for Mtb to survive, it must synthesize its own biotin, an essential cofactor that is involved in the biosynthesis of some fatty acids (e.g. mycolic acid), from pimeloyl-CoA7. During infection, Mtb primarily resides in macrophages, which, normally,…

Abstract: When an acid and a base combine, the base neutralizes the acid in a chemical reaction. This is how an antacid works (Gomez). During this project, we will test which of the 3 generic brand antacids chosen are most potent in neutralizing lemon and grape juice. This can be helpful in a real life situations, if you are experiencing heartburn, acid reflux, and/or dietary problems. This experiment will help you decide which antacid actually diffuses the acid in your stomach and has the…

Methods Some setup was required to conduct this experiment. The materials needed were five transplants, soil, carbonated water, vinegar, five clear plastic containers, an aluminum tray, and pH strips. The transplants used in this experiment were romaine lettuce transplants (Lactuca sativa). Each of the five plastic containers were punctured underneath to allow for water drainage. Each container was received a transplant and was filled with soil. The five conditions tested were the control…

amount of oxalic acid in the sample solution. The analyte solution containing oxalic acid was added with sulfuric acid and heated prior to the titration with permanganate. The persistent pink color signaled the end of the titration. The amount of the oxalic acid in the solution was found to be 8.941%. The redox titration was precise in the quantification of oxalic acid with a standard deviation of 1.327%. Introduction One of the natural organic compounds found in plants is the oxalic acid. It…

The developed method consisting the mobile phase 3g of Docusate Sodium was dissolved in 580 ml of Methanol, sonicated to dissolve to this 420 mL of milli Q water was added and pH was adjusted at 3.0 with perchloric acid with isocratic programming, XTerra RP 18 column (250mm×4.6mm, 5μm) column as stationary phase with a flow rate of 1.0 ml/minute. Proposed method was found to be linear in the concentration range of 18.80 to 56.60 µg/mL for Aminexil and 25.00 to 75…
