Please can anyone help me with the following:
Filter paper is a poor material on which to powder a solid before introducing it into a melting tube. Why?
There are a number of reason I wouldn't use filter paper to break up a solid.
1. It isn't strong enough to withstand vigorous grinding.
2. The powder will be mixed with fibers of paper which will then become part of the melting process.
3. An extension of #2 is that the cellulose COULD affect the melting point due to mixed melting.
4. A small amount of sample (a few milligrams) will be lost on the paper during grinding and/or will not be transferred to a melting tube.
the melting point of pure benzoic acid and pure naphthol are 122.5 and 123 degrees celcius respectively. you are given a pure sample that is known to be either pure benzoic acid or 2- naphthol. describe a procedure you will use to determine the identity of the sample.
I don't know the answer
