Document Summary
Midterm 2 november 16, 2005: a specific phosphate complex absorbs light at 380 nm. Mixing a solution containing phosphate with a reagent a will produce this complex. When a 2. 00 ml urine specimen was treated with reagent a and then diluted to. 100ml, the measured absorption of this solution at 380 nm was 0. 428. A second identical 2. 00 ml aliquot was mixed with 5. 00 ml of 0. 0300 mg/l phosphate solution, and then diluted to 100ml to give an absorption of 0. 538 absorption units. A) what was the phosphate concentration in the urine. Name: _____________________: discuss the principal of operation of absorption atomic spectroscopy using a flame as well as atomic emission using an icp. Midterm 2 november 16, 2005: define and distinguish between the following, pmt and pda, red shift and blue shift. Ej kt s = (xi - x)2 (n -1)
