Jastin Mae M. Villanueva. Godwilling, an incoming Chemical Engineering sophomore from that university near Philcoa.
That wretching feeling you get when your friends are able to themselves through painting colors through words in their AH GE subjects (Comm 3, CW 10, whatever) and your poor imagination is unfortunately confined with writing things like…
“The aim of the experiment is to make use of spectrophotometry in determining the equilibrium constant of the formation of the complex FeSCN2+ from Fe3+ and SCN-. The experimentally obtained Keq of the reaction is -1040.76, which differs from the literature value (890) by 2561.37%. At room temprerature, the absorbances of five 10-milliliter-standard solutions were read using the Sequoia-Turner Model 340 Spectrophotometer whose light has a wavelength of 447 nm. The calibration curve was then constructed by plotting the absorbance readings over the equilibrium concentration of FeSCN2+, which corresponded to the initial concentrations of SCN- in this case. Then, the absorbances of two 10-mL, one 11-mL, one 12-mL and one 13-mL-unknown solutions were read using the spectrophotometer and they were used to calculate for the equilibrium concentration of FeSCN2+, which would eventually lead to the calculation of the equilibrium concentrations of Fe3+, SCN- and then the Keq of the reaction. It was concluded that even though negative equilibrium concentrations of Fe3+ and SCN- and negative Keq were obtained, spectrophotometry is indeed a way of obtaining the Keq of a reaction.”
Well, it’s not that I’m complaining about this (even if Chem 17 makes us cry blood, I have to admit that I do enjoy writing formal reports, RDRs, whatever) but I kinda wish that I have an outlet of creativity like, say, CW 10.
Maybe, someday Godwilling.
Next on my Literature Thingimajig (or maybe not): Some letter to my Math 53 professor. Pero baka near the end of the sem na. Ewan.
