22‚ 2012 Name: Cristhian Valor Organic Laboratory Pre-Lab 1. Main reaction sequence including side reaction products: 2. 3 Sentence Summary of the Experiment: The OH group on the benzene ring in salicyclic acid reacts with acetic anhydride to form an ester functional group. Thus the formation of acetylsalicyclic acid (aspirin) is referred to as an esterification reaction‚ which requires the presence of H+ (H2SO4 in our case). The technique used to purify the aspirin content is called

existing pores and voids‚ density is represented by the ratio of its mass and volume. It is given by the equation ρ= massvolume 1. The SI unit of density is kg/m3. However‚ its CGS units‚ g/cm3 or g/ mL‚ are the most commonly used ones in the laboratory. The conversion is given by 1 gcm3=1gmL=1000 kgm3 [1]. The density of a homogeneous liquid is also defined by the amount of mass per unit volume. Liquid is usually confined in a container‚ so its volume is relative to the volume of its container

successful. The gel ran well‚ and the proteins from the gel were successfully transferred to the membrane provided in the kit. Introduction The name western blot was given to the technique by W. Neal Burnette and is a pun on the name Southern blot. Southern blot was a name given by Edwin Southern to a technique he developed for DNA detection. Western blot analysis has the ability to detect one specific protein in a mixture of any number of proteins while at the same time giving you information
