Experiment 5B: Ketone Reduction Objective: Using sodium borohydride as a reducing agent‚ the ketone 4-tert-butylcyclohexane is reduced to its corresponding alcohol. It is purified through extraction techniques to give the cis and trans diasteromer products. Procedure: The procedure was followed as outlined in Mayo’s book for Experiment 5B with the following modifications: 1. Reagents and Equipment – The reaction will be on a scale of 2X what is described in the text. 2. Reagents and Equipment

There are different kinds of compounds‚ ionic‚ covalent‚ and acidic and over all of this the atoms making up the compounds are either binary or polyatomic. The simplest compounds to name are binary ionic compounds‚ for example NaCl‚ which is named Sodium Chloride. Na having a positive oxidation number goes first followed by Cl which having a negative oxidation number goes last and is changed from Chlorine to chloride the -ide indicating its negative charge. Of course‚ the

The chemical equation for Thiopental Sodium is C11H17N2NaO2S. First synthesized in 1935‚ the proper name for the drug is Thiopental Sodium it also goes by Sodium Pentothal but that is actually a trademark of the drug ’s manufacturer‚ Abbott Laboratories. A yellow water-soluble crystal‚ it is classified as an ultra-short acting barbiturate‚ a type of drug that depresses the central nervous system‚ slowing the heart rate and lowering blood pressure. Widely used in medicine as an anesthetic during surgery

Material and Methods * Osmosis : -thistle funnel tube -dialysis tubing sack -saturated NaCl w/food coloring -beaker with distilled H2O The experiments begins with the construction of a simple osmometer by obtaining pre-soaked length of tubing ‚opened and tied at the end. The tube is filled with saturated NaCl solution (with added food coloring) and the thistle is inserted in the dialysis tubing. The dialysis tubing is sealed to the thistle funnel with dental floss and placed in a beaker

In this lab experiment‚ we used sodium bicarbonate to influence photosynthesis. Sodium bicarbonate is a formula of NaHCO3 (baking soda). In this lab experiment‚ we observed photosynthesis in spinach leave and investigated the effect of sodium bicarbonate on photosynthesis. The experiment was to determine how many disks of spinach leaves float at the end of every ten minutes. Our main focused and question was how using different amount of concentration of sodium bicarbonate would affect the process

Bacon‚ Toast‚ Sodium Nitrate and Potassium Bromate For Breakfast Samuel Martino Have you ever looked at the ingredients on the side of a food package? There is a lot more than the main food in the package. Usually it has real food then several different chemical compounds and preservatives listed behind the real stuff. In some foods the ingredients include chemical compounds as sodium nitrate and potassium bromate. Sodium nitrite is an ionic compound and is identified by the chemical formula

Sodium was first discovered by Sir Humphrey Davy in 1807. This element is the 11th element found on the periodic table; located in group 1 and period 3. Its chemical symbol is Na and it is classified as a metal. Metals‚ by definition‚ means that they are elements that are luster‚ lose electrons very easily‚ malleable‚ ductile‚ and are great conductors of heat and electricity. Sodium is found in group 1 of the periodic table because the electronegativity of sodium is very low. This allows it to form

EXPERIMENT: 1 Object: To find the wavelength of Sodium light by Newton’s ring. Apparatus required: A Plano convex lens of large radius of curvature‚ optical arrangement for Newton’s rings‚ plane glass plate; sodium lamp and traveling microscope. Formula used: The wavelength of light is given by the formula λ =D n2+p –Dn2 / 4pR Where D n+p = diameter of (n+p)th ring Dn = diameter of n th ring‚ P = an integer number‚ R = radius of curvature of the curved face of the Plano- convex lens.
