If you place two spots of the same pure compound one vertically above the other on the plate (so they lie on the same path while the solvent carries them up the plate), would they be closer together, further apart, or would the separation remain the same at the end of the run? Explain. Include a mathematical explanation assuming the following initial conditions. The plate has a total height of 10.0 cm. The lower spot (A) is placed at 1.0 cm from the bottom of the plate and the upper spot (B) is placed at 3.0 cm from the bottom of the plate. The plate is removed when the solvent rises to 1.0 cm from the top of the plate. The R, of the compound is 0.50 in this solvent system. For each of the two spots: What is the effective solvent distance for each trial? What distance is moved by the sample in each trial? How far apart are the two samples initially and at the end of the run?

1. The entire mercury bulb of the thermometer must be below the level of the side arm in order to obtain an accurate reading of the distillation temperature. Why is this so?2. Why is cold water circulated through the condenser from the bottom rather than from the top?4. In most distillations, the total volume of liquid obtained (distillate + residue) is not equal to the volume of the mixture introduced into the flask. What are the possible sources of loss in this procedure?
A student properly sets up a column chromatography experiment. Although the mixtureis soluble in the mobile phase, the sample appears "stuck" at the top of the column and willnot elute regardless of how much solvent is applied. What could be the cause of this prob lem and what could the student do to try and achieve a successful separation?
In this experiment, the problem is that the volume of the volumetric pipet is not accurately known (only 2 sig figs), so any density calculation will also be limited to 2 sig figs. Calibration increases the number of sig figs from 2 to 4. As a result, the density also increases from 2 to 4 sig figs. Explain how and why this is possible.
