Recovering KNO3 from Aqueous Solution at 10°C

[synergix]

Homework Statement

The mass of potassium nitrate that could be recovered from a solution prepared at 60deg Celsius from 250g potassium nitrate and 250g water by cooling the solution to 10 deg Celsius.

The Attempt at a Solution

not to sure how to start this one any help would be appreciated

at 60oC the solution can be saturated> 1:1 ratio so I figure once I know the solubility at 10oC I simply multiply 250g by the ratio? I am not to sure what the solubility of KNO3 at 10oC is

my first step would be to determine the solubility of potassium nitrate (KNO3) in water at both 60°C and 10°C. This information can be found in a solubility table or by conducting a solubility experiment. Once the solubility is known, I can calculate the amount of KNO3 that would remain dissolved in the solution at 10°C, based on the initial amounts of KNO3 and water used.

Next, I would consider the process of cooling the solution. As the solution cools, the solubility of KNO3 decreases, causing it to crystallize and precipitate out of the solution. The rate and efficiency of this process would depend on factors such as the rate of cooling and the concentration of KNO3 in the solution.

In order to accurately determine the amount of KNO3 that can be recovered, I would also need to take into account any losses that may occur during the cooling and recovery process. For example, some of the KNO3 may remain dissolved in the solution, or it may adhere to the walls of the container.

Overall, the amount of KNO3 that can be recovered from the solution at 10°C would depend on various factors and would require further experimentation or calculations to determine an accurate value.
