CHEMISTRY DETERMINATION OF ENTHALPY CHANGE OF NEUTRALIZATION IA Criteria Assessed: DCP CE MS Introduction When an alkali neutralizes an acid‚ a salt and water are formed. Aqueous hydrogen ions (H+(aq)) from the acid react with the hydroxide ions (OH- (aq)) from alkali‚ forming water. The identity of salt will depend on the nature of the acid and alkali used. H+(aq) + OH- (aq) → H2O(L) The combination of H+ and OH- ions in this way releases energy. In this practical‚ the

Spectrophotometric Methods: The Determination of Iron The goal of this laboratory experiment was the quantitative spectrophotometric determination of Fe (II) by using a calibration plot‚ which obeyed the Beer-Lambert Law. In order to determine the Fe (II) concentration‚ a series of solutions of known concentrations were made. The solutions were analyzed by the Ocean Optics spectrophotometer in order to determine their absorbance. The concentration of the unknown Fe (II) was determined by the “eye-ball”

Complexometric Determination of Water Hardness Abstract: Create a standardized EDTA solution for use as a titration solution to determine the hardness of water from a single random sample. Introduction: Using a calibrated EDTA solution to determine water hardness from a random sample. Essentially the Na2EDTA solution reacts one to one with the mineral content of a sample of tap water and by use of a standardized solution a ppm estimation can be obtained for the hardness of water.

Checkpoint: Patient Self-Determination Act The Patient Self-Determination Act (PSDA) was legislated by Congress in 1990 as part of the Omnibus Budget Reconciliation Act (OBRA). Congress felt that individuals has the right to determine their final healthcare. In a Ambulatory Surgery facility setting‚ Medicare/Medicaid requires that each patient sign a HIPAA form‚ explaining their rights prior to the procedure being performed. The purpose of the PSDA would be to ensure that individuals are provided
