Answer:

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

Explanation:

Assuming 2mg of impurity B to be present

100 mg of A is present as well

<u>Method of purifying A given that B is of same solubility </u>

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
