Lactic acidosis URL of this page: http://www.nlm.nih.gov/medlineplus/ency/article/000391.htm Lactic acidosis is when lactic acidlactic acid builds ups in the blood stream faster than it can be removed. Lactic acid is produced when oxygen levels in the body drop. Causes Causes The most common cause is intense exercise. However‚ it can also be caused by certain diseases‚ such as sepsis‚ respiratory failure‚ cardiac failure‚ AIDS‚ cancer‚ and kidney failure. Metformin‚ a common

However‚ the sodium hydroxide test supported that it was actually calcium‚ as a white precipitate was formed during this test. The chemical equation for this test is: CaCl2(aq) + NaOH(aq) Ca(OH)2(s) + NaCl(aq) I identified it to have chloride ions present as during the silver nitrate test a white precipitate was formed.

Synthesis of 1-Bromobutane from 1-Butanol Reference: Discovering Organic Chemistry in the Laboratory; John R. Ganson Ph. D‚ Revised 2011 by Alfredo Mellace Ph. D www.Aldrich.com Purpose: To synthesize 1-bromobutane from 1-butanol via SN2 reaction. Alcohols are converted into the alkyl halides adding an aqueous solution sodium bromide. The sulfuric acid acts as a catalyst in converting the OH functional group of butanol‚ to a better leaving group. In order for this reaction to synthesis 1-Bromobutane
