This question addresses a variation on a classic elementary chemistry
question: what is the best way to separate a mixture of salt, sand and
water? The usual answer is filtration followed by distillation. Suppose
that we distill first. How can the salt and sand then be separated? Can
we heat until either the salt or sand melts, separating the two
substances at that point?
