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

Abstract- Expirement 1: Precision‚ Accuracy‚ and Density Measurements This experience is intended to introduce the proper use of the most used laboratory equipments and glasswear that is come upon in the lab. As well‚ to determine the mass‚ volume and density of water by using various types of measuring glasswear‚ such as beakers‚ graduated cylinder‚ pipet‚ etc... The measurement of the density of water will determine the precision and accuracy of these measuring glasswear. Also‚ there will be a

In order to obtain the data‚ the DataStudio™ software is set up on the computer to use the temperature sensor on the apparatus to collect steadily the temperatures at specified time interval of 5-seconds. After the computer is completely set-up‚ the rest of the apparatus is collected. Water is added to the calorimeter until it is about 2-inches away from being completely full. In order to lower the temperature of

Macbeth and ‘The Laboratory’? In this essay I will be writing about female power in Macbeth and ‘The Laboratory’. I will be analyzing them both to show the similarities and differences between the two pieces. Both include a strong‚ crafty and dominant female character and Shakespeare and Browning explore these characters fully and in great detail. Both the speaker in ‘The Laboratory’ and Lady Macbeth strive to maintain their innocent images. The speaker in ‘The Laboratory’ wants to kill

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
