In a synthesis experiment you obtain a sample of product on which you do a melting point determination and find a melting point range of 108.0 to 114.3 degrees celsius. the sample is supposed to be benzoic acid. what preliminary conclusion(s) can you reach from this one determination? (select true or false)
1) the sample is probably impure.
2) the sample is not benzoic acid
3) the melting point determination may need improvement -- it may not have been done properly, and make sure it was repeated at least once.
5) the sample probably needs recrystallization.
6) the sample may be benzoic acid.
