The solubility of acetanilide in hot water (5.5 g/100 ml at 100 C) is not very great, and it has some solubility in cold water (
0.53 g/100 ml at 0 C). What would be the maximum theoretical percent recovery from the crystallization of 4.0 g of acetanilide from 100 ml of water (assuming the solution is chilled to 0 C for filtration). Show your calculations.
The maximum theoretical percent recovery from the
crystallization of 4.0 g of acetanilide from 100 ml of water is 87%. I
am hoping that this answer has satisfied your query and it will be able to help
you in your endeavor, and if you would like, feel free to ask another question.
Maximum theoretical percent recovery of acetanilide is 86.8%
Explanation:
From the given information:
Solubility of acetanilide in 100 ml water at 100 C = 5.5 g
Solubility of acetanilide in 100 ml water at 0 C = 0.53 g
When 4.0 g of acetanilide is dissolved in 100 ml of water, all of it will go into solution. As the solution is cooled to 0 C only 0.53 g of it will dissolve.
Right now it's written in scientific notation, so you can just move the decimal place in 3.8 to the right 3 times (as it is times 10 to the third power) to get 3,800g.
