    Benedict's test uses a chemical which will react with reducing sugars (like glucose and fructose) to produce a precipitate. Since sucrose and starch are not reducing sugars, Benedict's test will be negative for them. However, the hydrolysis of sucrose produces glucose and fructose, both reducing sugars. So, if sucrose has been hydrolyzed, there will be reducing sugars present which will react with Benedict's reagent to give you a positive test. Similarly, hydrolysis of starch produces glucose which will react with Benedict's reagent.

    Will you get a positive or negative result when you test the solution of sucrose with Benedict’s reagent after hydrolysis has occurred? What will the test results look like

    Did you do the iodine test before and after some treatment that should have resulted in hydrolysis of starch? What were the colors of the two samples after adding iodine? What does iodine react with, and what color does it produce? If you think a bit about what you did and what you observed in the experiment, you should be able to answer your own question.
