salicylaldehyde. Introduction The purpose of this experiment was to determine the identity of an unknown organic liquid by measuring some of its physical properties. The properties were then compared to those of known compound to make an identification. The properties determined included density‚ boiling point‚ refractive index‚ and important absorption bands in the infrared spectrum. Experimental Unknown number 16 was obtained for the experiment. The unknown was an oily‚ colorless liquid

Chapter 2 Case Study Summary 1: 21-year old woman that has had type 1 diabetes for the past 8 years‚ was brought to the hospital in a coma. She was prescribed to take 92 units of insulin a day to maintain her sugar levels within normal limits and prevent excess sugar in her urine. Upon admission she was hypontensive‚ tachycardic and hyperventilating. Her labs show she is acidonic‚ arterial blood carbon dioxide levels were low‚ blood oxygen tension is normal‚ bicarbonate levels are

chromium(III)‚ which is green‚ when an alcohol is oxidized by the reagent. A change in color of the reagent from orange to green represents a positive test. Primary alcohols are oxidized by the reagent to carboxylic aicds; secondary alcohols are oxidized to ketones. Tertiary alcohols are not oxidized at all by the reagent. Hence‚ this reaction can be used to distinguish tertiary alcohols form primary and secondary alcohols. Procedures: 1. Place ethanol‚ isopropyl alcohol and tert-butyl alcohol in three

The present methodology offers several advantages‚ such as good yields‚ short reaction

of benzaldehyde and 5 drops of acetophenone. Based on these data‚ it is possible to find alcohol by oxidation and aldehyde by observing precipitation Introduction This experiments is to find if one substance has alcohols‚ aldehydes or ketones. If one reactant is alcohol‚ the color of the reactant will be turned into green when 6 drops of potassium dichromate and 1 drop of concentrated sulfuric acid were added. Also‚

We performed two procedures in which we reduced methyl acetoacetate. For the first procedure we produced a racemic mixture of Methyl (S)-3-Hydroxyacetate and Methyl (R)-3-Hydroxyacetate. For the second we produced only one of the enantiomer products depending on which enantiomer of Tartaric Acid was used. A reduction is a reaction which generally means adding more carbon-hydrogen bonds to a compound. In a reduction reaction the oxidation number of a carbon atom decreases. The opposite is an oxidation

The word ketosis often inspires confusion or even alarm in those trying to figure out what causes it and whether or not it’s a good thing. Here’s a simplified overview of ketosis. Ketosis Definition Let’s move from an over-simplified ketosis definition to moderately simple one. Ketosis means that the body has gone from using carbohydrates as its source of fuel to fats-almost exclusively. But it’s a little more involved than that. Ketosis starts when there aren’t enough carbohydrates in the blood

Urinalysis also called urine test. This test can help find conditions that may need treatment or detect some common disease‚ urine test help find serious diseases in early stages. It may take before surgery or people at high risk for kidney problems‚ diabetes‚ liver problems or any other metabolic conditions.

The diet is designed to induce the individual into a state of ketosis‚ ‘Ketone bodies are produced mainly in the mitochondria of liver cells. Its synthesis occurs in response to low glucose levels in the blood‚ and after exhaustion of cellular carbohydrate stores‚ such as glycogen. The production of ketone bodies is then initiated to make available energy that is stored as fatty acids.’ (Wikipedia‚ 2012). The individual is advised to consume

The method used to separate the components was Thin Layer Chromatography (TLC) with silica adsorbent as the stationary phase and 0.5% glacial acetic as the mobile phase. In one plate‚ five known samples were used as the reference‚ that is: Aspirin; Caffeine; Ibuprofen; and Salicylamide. Aspirin and Salicylamide were the only samples that fluoresced
