Document Summary
Curt kim, jonathan lee, keshav mantha, bobbie sheng. Goal: to determine the equilibrium constant of a certain chemical reaction using a spectrophotometer. In part a, four standard solutions were created using a combination of 0. 2m fe(no3)3, 0. 001m nascn, and 0. 1m hno3. The amounts of each compound that were added to each solution can be found in the table below. Once these four solutions were prepared, a blank solution was also created using only fe(no3)3 and hno3, which was then inserted into the spec-20 machine and used for calibration. Then, each of the four standard solutions was poured into a small cuvet and its absorbance in the spec-20 was recorded to conclude part a. In part b, four test solutions were made from the same three compounds; their concentrations were 0. 002m (fe(no3)3), 0. 002m (nascn), and 0. 1m (hno3). Once the spec-20 was recalibrated using the blank solution, each test solution was inserted into the machine and recorded as well.
