a you can control the solubility of the substance in the mixed solvent.
b you don't have to know the exact amounts of the solvents needed.
c you can quickly make the solution supersaturated by adding more of the solvent with less dissolving power.
d you can quickly make the solution supersaturated by adding more of the solvent with greater dissolving power.
e you can calculate the precise amounts of the solvent needed for recrystallization.
i chose b and e but got it wrong. i'm not sure if it's because i chose the wrong ones, or i didn't choose all of the correct answers.
i've looked through my notes and textbooks many times, but i'm still a bit confused about this. ! ?
