Question
This process can be accomplished through freezing and thawing, as ions are rejected during crystal formation. For 10 points each:
[10m] Name this process, often performed via vapor-compression or multi-stage flash distillation, that uses energy to remove solutes.
ANSWER: desalination [or desalinating]
[10e] Another common desalination method is the "reverse" form of this process. Normally in this process, water diffuses across a semipermeable membrane to the side with more solutes.
ANSWER: osmosis [or reverse osmosis]
[10h] This other technique desalinates water by pulling cations and anions across respective ion-exchange membranes using an electric current. This technique occurs in namesake stacked, fluid-filled "cells."
ANSWER: electrodialysis [or electrodialysis reversal]
