Question
Indicate whether each of the following experimental "blunders" would produce a high result, a low result, or make no difference in the value obtained for the concentration of CuSO4 unknown solution. a. The wavelength of the observed maximum is recorded as a value less than the observed wavelength. b. In making the "working curve" the CuSO4 solution concentrations are twice as large as reported. c. The unknown solution is spilled in placing it in the cuvette. Additional unknown solution is added to the cuvette.Explanation / Answer
1. when you make light go trough a sample you can determinate the wavelenght at which the sample absorbs. If you recorded a lower value, then if you want to determinate the concentration of a sample, the concentration values will be lower, this happens because just little part of the sample will react to light.
2. In uv spectroscopy you must have very low concentrations. If the concentrations are larger, the spectroscopy is not accurate.
3. the concentrations of the sample in the cuvette will be not constants.
