FAQs on Purification of Benzoic Acid by Crystallization Video Lecture - Class 11
| 1. What is the purpose of crystallization in the purification of benzoic acid? |  |
Ans. Crystallization is used as a purification technique for benzoic acid because it allows for the separation of impurities from the desired compound. By dissolving benzoic acid in a solvent at high temperatures and then gradually cooling the solution, pure benzoic acid crystals can form while impurities remain in the solution.
| 2. Which solvents are commonly used for the crystallization of benzoic acid? | |
Ans. Some commonly used solvents for the crystallization of benzoic acid include water, ethanol, and methanol. These solvents are chosen because they have different solubility properties that allow for the selective precipitation of benzoic acid crystals.
| 3. How does temperature affect the crystallization process of benzoic acid? | |
Ans. Temperature plays a crucial role in the crystallization process of benzoic acid. When the solution is heated, the solubility of benzoic acid increases, allowing it to dissolve completely. However, as the solution cools, the solubility of benzoic acid decreases, resulting in the formation of crystals. By controlling the cooling rate and temperature, the size and purity of the crystals can be optimized.
| 4. Can impurities be removed completely through the crystallization process? | |
Ans. While crystallization is an effective method for purifying benzoic acid, it may not completely remove all impurities. Some impurities may still be present in the crystals, although in much lower concentrations compared to the original solution. Additional purification steps, such as recrystallization or filtration, may be required to further purify the benzoic acid if necessary.
| 5. How can the purity of the benzoic acid crystals be determined? | |
Ans. The purity of the benzoic acid crystals can be determined through various analytical techniques. One common method is to compare the melting point of the obtained crystals with the known melting point of pure benzoic acid. If the melting points match, it indicates a high degree of purity. Other techniques, such as spectroscopy or chromatography, can also be employed to assess the purity of the crystals.
