cooled to 25°C, then 10 g of the compound would remain dissolved in the mother l
Here's how to solve this problem:
Step 1: Calculate the amount of water required to dissolve 10g of the compound at 25°C. The solubility of the compound is given as 6.8 g per 100 mL of water at 25°C. This means that 6.8 g of the compound can be dissolved in 100 mL of water to form a saturated solution at 25°C. To find the volume of water needed to dissolve 10 g of the compound at this temperature, we can set up a proportion: Solving for : This is the amount of water that would be saturated with 10 g of the compound at 25°C. If this amount of water is used in a crystallization process, and the solution is cooled to 25°C, then 10 g of the compound would remain dissolved in the mother liquor.
Step 2: Determine the maximum possible yield percent. The question asks for the maximum possible yield percent if the pure compound is collected at 25°C. This implies that the "10g of the compound" mentioned in the first part is the initial amount of compound we are trying to crystallize. To achieve the maximum possible yield, we must assume that the compound is dissolved in the minimum amount of hot solvent, and then cooled to 25°C. The amount of compound that remains dissolved in the mother liquor at 25°C is considered the loss.
Since the solubility at a higher temperature is not given, we assume that the 10 g of the compound is dissolved in a minimal amount of hot water, and then cooled to 25°C. The amount of compound that remains dissolved in the mother liquor at 25°C is the amount lost due to solubility. From Step 1, we found that 147.06 mL of water can dissolve 10 g of the compound at 25°C. If we start with 10 g of the compound and use 147.06 mL of water, then at 25°C, all 10 g would remain dissolved. This would result in a 0% yield, which is not a "maximum possible yield".
This suggests a common simplification in such problems: the "amount of water required to crystallize 10g of the compound" is the amount of water that will be present in the mother liquor after the crystallization, and the 10g is the initial amount of compound. However, the phrasing "maximum possible yield percent" usually implies that the only loss is due to the solubility at the collection temperature, and that the initial amount of compound is dissolved in the minimum possible volume of solvent at a higher temperature.
Given the ambiguity, let's consider the most direct interpretation for "maximum possible yield percent" when only one solubility is given: If we start with 10 g of the compound, and we want to maximize the yield, we would ideally want to recover all of it. However, some amount will always remain dissolved in the mother liquor at the collection temperature (25°C). The problem does not specify the volume of water used for the crystallization. Without knowing the volume of water used, we cannot calculate the exact amount lost.
However, if the question implies that the "10g of the compound" is the initial amount and we are asked for the maximum yield, it often means we should consider the scenario where the entire 10g is the amount that could potentially be recovered, and the solubility at 25°C represents the loss per 100 mL of water.
Let's assume the question implies that the "10g of the compound" is the initial amount of compound. And the "amount of water required to crystallize 10g of the compound" is the amount of water that must be used to dissolve this 10g at a higher temperature, such that when cooled to 25°C, the maximum yield is obtained.
If we assume that the 10g of compound is dissolved in the minimum amount of hot solvent, and then cooled to 25°C. The amount of compound that remains dissolved at 25°C is the amount lost. The amount crystallized is . Yield percent = .
Without solubility at a higher temperature, we cannot determine the minimum volume of solvent. This problem is missing crucial information for a standard crystallization yield calculation.
However, if we interpret "maximum possible yield percent" as the percentage of the initial 10g that can be recovered, assuming that the amount lost is due to the solubility at 25°C in some unspecified minimal volume of solvent. This is still problematic.
Let's assume the question is simplified and the "10g of the compound" is the initial amount of compound.
