8. For each of the following situations, predict whether the experimentally determined concentration of an unknown solution would be greater than, less than, or unchanged from the theoretical value. Explain your reasoning in each case. a. The spectrophotometer is not zeroed, so all absorbance readings (for known and unknown solutions) are 0.010 too high. b. The spectrophotometer is not zeroed in preparing a calibration curve, so that all absorbance readings for the knowns are 0.010 too high. However, the instrument...

Briefly explain the possible effect of the following experimental errors. TLC plate procedure with drug concentration. 1. You used a 1:200 ratio of ethyl acetate/acetic acid rather than 200:1: (Note: ethyl acetate is significantly less polar than acetic acid)  2. You allowed the TLC plate to develop too long (past the point where the solvent reaches the top of the plate). 3. You used a plastic pipet rather than a thin glass spotter. 4. You labeled your plate using a...
