What would be the effect on the observed melting point if sample was too small?

Using too large of a sample when determining its melting point will flaw your results since, if the sample is too large it will be harder for the sample to melt in the melting point apparatus.

∙ 9y agoWe would need far more detail in order to even begin to guess why there might be any effect. The melting point of a substance is an intrinsic property; it shouldn't depend on the amount of substance being melted.

∙ 9y agoThe melting point is an intensive property and is independent from the size of the sample.
But working with very small samples is more difficult and more errors are possible.

When work with very small samples the determination is more difficult and the result may be not so precise.

What criterion is used for the purity of a sample of caffeine?
The closer the melting point of the sample of the caffeine you have extracted, to the known melting point of pure caffeine, the more pure your sample is.
How does the melting point of the crude sample compare with that of the purified sample?
An impure sample will have a lower melting point, and will also have wider melting point range than that of a pure sample of the same substance. a sharp melting point range can also indicate a eutectic mixture
How fast do you heat the sample when determining a melting point?
The apparatus used for determining the melting point will heat the sample at an appropriate rate. All you need to do is watch and note the point at which the sample melts, as should be demonstrated to you by your lab supervisor.
What is the term of melting point range?
The crystalline solids have a sharp melting point say 87oC but most of the amorphous solids do not have a sharp melting point they have a range of melting say they started melting at 87oC and continue till 89oC.
Why is it important to determine the melting range of the impure and recrystallized sample of vanillin?
The melting point is an indication of purity.
What effect would contaminating the sample with an insoluble impurity have on the melting point?
Soluble impurities (that is, impurities that are included within the crystal matrix) tend to lower the observed melting point and broaden the melting point range. Insoluble impurities have no effect on the melting point. Found from website: http://swc2.hccs.edu/pahlavan/2423L1.pdf
Why will the observed melting point range be lower than true value if we heat the sample too fast?
A lower and wider melting point range could indicate that the sample was contaminated with trace amounts of impurities.
When the observed melting point is less than the stanadr value what inference will you get?
The substance whose melting point is being observed is impure.

What Would be the effect poorly packed in melting point?
The effect of poorly packed will decrease the melting point.

What is a capillary melting point?
The sample is placed in a sealed capillary and heated up to the melting.
How would you determine the purity of the solid crystals in crystallization?
One of the easier and more reliable ways to check if a solid compound is pure after re-crystallization is to check its melting point. Impurities will always lower the melting point of a sample, and the more impure, the lower the melting point will be. By checking the melting point of your sample with a reference value from a book or reliable internet source, it can be determined exactly how impure the sample is. If perhaps your compound is unknown, and thus are unable to obtain a reference value, you could obtain melting point of the sample, and then re-crystallize a few more times, obtaining a new melting point each time, until it is unchanged by re-crystallizing. This will of course decrease your yield, but if there is little fluctuation in your series of melting points, you can be sure you have a relatively pure sample.
