Acetone

arterial blood and urinalysis, Di’s blood has a pH of 7.0 (normal range 7.35-7.45), her blood is too acidic and her urine as well as blood both have ketone bodies present. It is determined that Di has ketoacidosis, the lab results in combination to the acetone like odor from her breath. Ketoacidosis occurs when acetoacetic acid and beta-hydroxybutyric acid accumulate. Without the sufficient amount of insulin the body still remains in the fasting state despite she has ingested food. The liver…

Introduction Phytoplankton require nutrients and light to survive. Certain nutrients are a limiting factor in phytoplankton competition and composition. Some phytoplankton are limited by nitrogen while others may be limited by phosphorus (Quigg, 2016). The experiment in this paper will determine if a body of water is limited by nitrogen or phosphorus by running a resource limitation assay. Nutrient levels in bodies of water may change seasonally in a natural way (Vanni and Temte, 1990).…

1.2.2. Physical Properties Methyl ethyl ketone is a clear, colourless fluid that is less viscous than water and has a somewhat acute odor that smells most of the ketones and is described by some as being similar to Boerscot. Compared with acetone it is less volatile and less soluble in water (about 27.5g / 100mL at room temperature). It is a solvent used for extracting gums and oils from plants and cleaning the remnants of metal and glass, so why often a cleaner or ingredient is found 1.2.3.…

art. There are several types of cleanser with different functions. The first one is nail polish remover. It is used when you are going to erase all the nail polish on our nails. Nail polish remover is usually acetone, but it tends to makes your nails chip. So, better to use a non-acetone nail polish remover to avoid that problem. The second one is nail polish correcting pen. It is like a marker that contains nail polish remover in its body. There also the tip where you can change it if it no…

The goal of this experiment was to use chemistry to analyze an unknown compound and through testing its physical and chemical properties determine what unknown compound that was found in a landfill. This would benefit the Environmental Protection Agency because once they know what the substance was they could determine the best way to remove it from the landfill and if there were any potential safety hazards to beware of while handling the substance. This would prevent any accidents that may…

Mannitol was from Spectrochem, Mumbai. All the solvents; methanol, acetone and DCM was purchased from Fischer Scientific. Preparation of nanosuspension: Nanosuspension was prepared by antisolvent precipitation method. The effect of various factors on the particle size, pdi and zeta potential of the formulation was carried out by single factor experiment including stabilizers (PVP K30, HPMC, F68, F127, PEG4000), organic phase species (acetone, methanol, DCM), volume of organic solvent and speed…

In 2014 alone, there were more than 42,700 people arrested for drunk driving across the state of Florida. As you are likely aware, the results from breath tests administered by the authorities are often used as grounds to make such arrests, and as evidence of intoxication at trial. In an effort to ensure the accuracy of these types of tests, the instruments used to conduct them are regularly inspected and calibrated. Breath tests used by law enforcement agencies in the state of Florida must be…

Title: Stoichiometry to Calculate Reaction of Zinc and Iodine and Law of Conservation of Mass Authors: Sang Nguyen and Sami Biro Introduction II. Materials and Methods A. Materials Zinc (Zn), iodine (I2), acetone (C3H6O), acetic acid (C2H4O2) and zinc iodide (ZnI2) were used to conduct this experiment in order to confirm the validity of the law of conservation of mass as well as to use Stoichiometry to calculate the reaction between zinc and iodine. There are some precautions that one must…

5. Protein purification There are many thousand kinds of proteins with different properties and functions in a cell. Proteins have been purified in active form on the basis of such characteristics as solubility, size, charge and specific binding affinity. Normally, protein mixtures are subjected to a series of separations, each based on a different property to yield a pure protein. 5.1 Separation based on solubility (Scopes, 1994) The protein solubility in various solvents depended on the…

employed for the construction of novel indole–benzimidazole-based 1,2,3-triazole hybrids is demonstrated in Scheme 1. Compound 2 was prepared by treating propargyl bromide with 1H-indole-3-carbaldehyde (1) in presence of potassium carbonate in dry acetone at reflux temperature [26]. Compound 2 was further reacted by heating at reflux temperature with o-phenylenediamine (OPDA) in chloroform for 6 h afforded compound 3. Compound 3 coupled with variously substituted azides by Azide-Alkyne…
