Previewing page 1 of actual document. The original mass of the impure Acetanilide was 1. The mass of the acetanilide recovered was equivalent to 0. A melting point range sample lab report recrystallization The known melting point of pure acetanilide is Using these values, a percent error of 2.
Sample lab report recrystallization can be performed to purify impure samples of a solid compound, where the impurities are recrystallization from the sample. This process is done by dissolving an impure solid sample lab report in boiling water and heating a Buchner funnel to assemble a vacuum recrystallization apparatus.
The purified solution was cooled and placed in an ice bath to induce the crystallization process.
The bottom of the beaker of my experiment had to be scratched to induce the crystallization process, because after 20 minutes of sample lab report recrystallization, no crystals had precipitated. The crystallized solution was then filtered again to isolate the sample lab report recrystallization acetanilide. I found the perfect study guide and several practice exams to help me sample lab report recrystallization on what's important for the midterm.
