Question
DAta on the impure Benzoic acid
Mass of the benzoic acid + weighing paper 1.24g
Mass of weighing paper 0.24g
Mass of impure benzoic acid 1.00g
Data for recrystallized benzoic acid
Mass of recrystallized benzoic acid 1.16 at initial and final is 1.22
Mass of weighing paper is 0.24 at initial and final is 0.24
Mass of recrystallized benzoic acid is 0.98 at initial and final is 0.92
The calculation of percentage recovery is 98%
The result and discussion of Recrystallization of Benzoic acid If you took a melting point of a compound you synthesized,what is the true litersture melting point? How well does your melting point compare? What does your melting point indicate about the purity of the compound?
Explanation / Answer
Melting point benzoic acid : 125 - 126 deg C (recorded)
121 - 122
