Synthesis of Salicylic Acid and Potentiometric Determination of its Purity and Dissociation Constant ------------------------------------------------- Abstract The purpose of the study is to synthesize salicylic acid from the ester‚ methyl salicylate‚ and determine the acid’s dissociation constant and purity. The ester was converted to salicylic acid by base hydrolysis. The products were refluxed and recrystallized‚ to ensure maximum purity‚ and filtered‚ dried‚ and weighed. The melting point

I was at the cinema watching “Yes Man”‚ an American comedy‚ starring Jim Carrey. I found it hard to concentrate at the very end as three old‚ serious-looking men were deep in discussion. I was just about to ask them to be quiet when I realised that they were discussing the representation of bureaucracy portrayed in “Yes Man”. It is through the discussion of these three men : Max Weber a German sociologist and economist ‚ Robert Merton an American economist and Michel Crozier a French sociologist

It is interesting to think about how television could possibly affect your attention span. In Postman’s “Amusing Ourselves to Death” (1985)‚ he states a particular fact that “the average length of a shot on network television is 3.5 seconds‚ so that the eye never rests‚ always has something new to see.” This fact alone shows that your attention is constantly shifting and changing focus to see what else is there or what is coming next. With the coming of the internet age‚ written narrative is coming

rhetorical analysis‚ and synthesis‚ instructed by Dr. Tina Giovanielli. Although I believe all four arguments were strong‚ for the purpose of this reflective assignment I am going to choose one argument that I think is my strongest piece of writing then analyze it and explain why I think that is my best work. I believe my last assignment (synthesis) was very challenging at first but it ended up to be my strongest piece in the whole semester. Since I have never done any synthesis before this one‚ I found

Effects of Differentiation on Enzymatic Activity Introduction HL-60 cells are capable of undergoing differentiation to induce different cell types. HL-60 cells can undergo morphological changes‚ changes in gene expression‚ and changes in protein synthesis. In the past weeks‚ we were able to conclude that HL-60 cells treated with DMSO and HL-60 cells treated with PMA will differentiate into granulocytes and monocytes upon treatment (1). We were also able to observe that both types of treated cells
