Discuss with those in you laboratory section the consequences of incorrect sample loading, variable sample size, and rates of heating and how these factors might lead you to obtain an incorrect value of the melting point for your solid sample.
Homework Answers
The consequences of incorrect sample loading on incorrect value of the melting point for solid sample :
If the sample is loaded more than 3 mm height of the capillary tube or else the melting point will be high practically. The sample should be loaded up to 2-3 mm height of capillary tube
The consequences of variable sample size on incorrect value of the melting point for solid sample :
When the sample is smaller in size then it would be too small to observe the melting point accurately.
When the sample is larger in size then it would be too high to observe the melting point accurately.
Hence the sample size should be in middle to observe the melting point accurately.
The consequences of rates of heating on incorrect value of the melting point for solid sample :
Rapid heating of a sample will observe the wider range of melting point of the sample because in thermometer mercury rises quickly and that takes time for the sample to melt and absorb heat.
Slow heating of a sample will observe narrow range of melting point of the sample
Heating rate of 1 to 2 degree Celsius per minute gives accurate results.

How would a mixture of naphthalene and benzophenone behave on a TLC plate with hexanes / acetone as the eluent? Compare the polarity of these two compounds. Outline the most commonly used procedure for the purification of an impure solid material using the technique of recrystallization. Why is acetone such a popular solvent? Point out one drawback in terms of safety considerations. Your final product might be impure since you suspect decomposition might have occurred. When determining the melting point...

10) Suppose that you are asked to use a sample of size 50 to create a 95% confidence interval for a population mean. The lower limit of your interval turns out to be L and the upper limit turns out to be U. If you were to change the confidence level to 90% and use the same sample data to create a revised confidence interval, would it be correct to say that the revised interval would have a lower limit...

APPLICATION! 1. A nonscientist brings a water sample to your laboratory and asks you to determine why there was a fish kill in the nearby lake. Having recently finished this experiment, what might you tell that person about the legitimacy of a test for dissolved oxygen? What reasoning would you use to maintain the integrity of your laboratory? 2. Fish kills are often found near the discharge point of water from cooling waters at electrical generating power plants. Explain why...
