Best Answer

Acidifying the mixture before recrystallization helps in converting any impurities that may be present in the mixture into their respective acid forms, which are typically more soluble in water. This makes it easier to remove the impurities during the recrystallization process, resulting in a purer final product.

How can recrystallization separate a mixture?

Recrystallization separates a mixture by taking advantage of differences in solubility between the components. By dissolving the mixture in a suitable solvent at an elevated temperature, the less soluble component will precipitate out first as the solution cools, forming pure crystals. The more soluble component remains dissolved in the solution and can be separated from the crystals through filtration.


How is the melting of an impure compound expected to change with recrystallization?

During recrystallization, impurities are removed as the compound is dissolved and then slowly cooled to allow for the formation of pure crystals. As a result, the melting point of the compound should increase after recrystallization because the presence of impurities lowers the melting point of the compound.


Could the separation of the components of a mixture in this experiment have been done in a different order?

Yes, the separation of components in a mixture can often be done in different orders based on the physical and chemical properties of the components. For example, if one component has a significantly different boiling or melting point from the others, it could be separated first using distillation or recrystallization before proceeding with other separation techniques. Experimentation and understanding of the mixture components are important when deciding the order of separation techniques.


How do you prevent immature recrystallization?

To prevent immature recrystallization, ensure that the solvent is added slowly to the solution during recrystallization, use a minimal amount of solvent, and employ a suitable solvent system based on the solubility of the compound. Additionally, controlling the rate of cooling during recrystallization can help prevent premature crystallization of impurities.


What are examples of drug that can be used to acidify urine?

Common drugs that can be used to acidify urine include ammonium chloride and ascorbic acid (vitamin C). These drugs are often prescribed to help prevent the formation of certain types of kidney stones and to enhance the elimination of certain drugs that are excreted in the urine.

When doing recrystallization what observations would prompt you to perform hot filtration?

If there is a significant amount of solid impurities present in the hot solution, causing cloudiness or turbidity, then hot filtration should be performed. This will help remove the impurities before allowing the solution to cool and induce crystallization.


How insoluble impurities removed during recrystallization?

Insoluble impurities are removed during recrystallization by filtration. After dissolving the mixture in a hot solvent and allowing it to cool, the desired compound forms crystals while the insoluble impurities remain suspended in the solution. The crystals are then collected through filtration, separating them from the impurities.
