Recrystallization purifies chemical compounds in solvents. It works best when there is only a small quantity of impurities in the compound. Recrystallization, also called fractional crystallization, is a process that involves dissolving an impure compound in a solvent at a high temperature to create a concentrated solution and then cooling the solution slowly.
I. Introduction A. Objective The purpose of first part of this experiment is to first recrystallize impure acetanilide that is contaminated with dye methylene blue. Decolorizing charcoal will be used to purify the sample. The starting and ending weights of the acetanilide will be recorded to determine percentage of acetanilide recovered. Also, the melting points […]

Lab report for organic chemistry on recrystallization and identification. Report abuse. Solid that you are assigned in each part and report the weight of all three. Preparation of 2-iodobenzoic acid from anthranilic acid; Preparation of. The purpose of the lab was to purify Phthalic acid through recrystallization.
Best Answer: The purpose of recrystalization is to purify the compound being recrystalized. This may seem difficult but it is much easier and cheaper that other methods of purification. For example column chromatograpy could easily purify your aspirin but it would take several hours and the materials would cost a couple hundred bucks.
Lab Report: Recrystallization Abstract: The purpose of this lab was to purify an unknown compound by recrystallization. Taking an unknown compound and identifying it by purifying it from its impurities through the use of hot gravity filtration. Then to determine the unknown you were to take the melting point.
13 EXPERIMENT 2: Recrystallization and Melting Point Questions Attach answers to these questions on a separate sheet along with Experiment 2 Report. 1. What are the important solubility characteristics for a solvent for crystallization of an organic solid which is contaminated with a small amount of impurity?
Crystallization Lab Report Purpose: Crystallization is technique used by chemists to purify solid compounds. Crystallization is based on the principles of solubility of the compounds that tend to be more soluble in hot liquids than they are in cold liquids. So, the purpose of this lab is to know how to perform crystallization as a method for purifying impure substances.
