Question

if B is completely insoluble in water. Your description should include the volume of solvent required.6b) Assuming that 2 mg of the impurity B are present along with 100 mg of A, describe how you can purify A if B has the same solubility behavior as A. Will one crystallization produce pure A

Answer 1

1st step : mix the mixture with water that way A will dissolve while B will remain insoluble.

2nd step :To get B from the solution, filter the mixture and get B

3rd step : To get A from the solution evaporate the new solution

Step-by-step explanation:

Assuming 2mg of impurity B to be present

100 mg of A is present as well

Method of purifying A given that B is of same solubility

Dissolve the 100 mg of A with 30 mL

1st step : mix the mixture with water that way A will dissolve while B will remain insoluble.

2nd step :To get B from the solution, filter the mixture and get B

3rd step : To get A from the solution evaporate the new solution
