The solvent moves 3 cm in about 10 minutes. Why shouldn't the experiment be stopped at that time instead of waiting 75 minutes for the solvent to move 10 cm? Question 3 options:   More time increases the concentration of mixture components.   More time allows for better separation of components in a mixture.   More time decreases the concentration of mixture components.   Instructors don't like students to be finishing their labs too quickly.
