1. What effect would this have on the observed boiling point of the liquid being distilled when a student who was performing a distillation for the first time failed to position the thermometer correctly? The bulb was set too high.
2. The number of theoretical plates required to separate an ideal mixture of two components of boiling points TA and TB is given by the relationship under perfect conditions:
Number of theoretical plates required = 120 /TA - TB
Determine the numbers of theoretical plates are required to separate a mixture of cyclohexane and toluene? In practice, the actual number of theoretical plates essential may be as high as double the number predicted by this equation.
3. Suppose you have forgotten to add the boiling tones to your round bottomed distillation flask but the distillation is now in the progress. What should you do?
