DATE PERFORMED: JULY 20‚ 2007 SPECTROPHOTOMETRIC DETERMINATION OF EQUILIBRIUM CONSTANT FOR A REACTION ABSTRACT UV-VIS spectrophotometry is one of the most widely-used methods for determining and identifying many inorganic species. During this experiment‚ this spectrophotometry was used to determine the equilibrium constant‚ Keq‚ of the Fe3+(aq)+SCN-(aq)↔ FeSCN2+(aq) reaction. By determining the amount of light absorbed‚ the concentration of the colored FeSCN2+ solution was also quantitatively

General Chemistry II Lab (CHEM 1106) Determination of the Solubility Product Constant of a Salt Date Performed: March 1‚ 2011 INTRODUCTION If solid KHC4H4O6 is added to a beaker of water‚ the salt will begin to dissolve. The amount of solid diminishes‚ and the concentrations of K+(aq) and HC4H4O6-(aq) in the solution increase. When no KHC4H4O6 dissolves‚ the concentrations of K+(aq) and HC4H4O6-(aq) will not increase further and any additional KHC4H4O6 added after this point will remain

Title: Determination of Iron in Natural water by Spectrophotometry. Aim: To determine the iron in natural water by spectrophotometry. Abstract: The iron in natural water was determined by utilizing spectrophotometric analysis. That was done by measuring the absorbance of five Fe(oPH)2+3 standards at 510 nm. From that information‚ a calibration curve was plotted and used to find the amount of Fe2+ that was in two unknown water samples based on the absorbance readings obtained with them at 510nm. The

Whale Rider: Inner Strength and Determination The film Whale Rider opens with a man‚ Porourangi‚ standing next to his wife as she gives birth to twins. Unfortunately‚ the mother and the son do not survive leaving only the girl who is named Paikea. This greatly upsets Koro‚ Porourangi’s father. As the reigning chief of the Maori people‚ he would have taught Porourangi’s first born son in the ways of their ancestors to become the next chief (Wald 2006).
