Question

a mixture of sand and isopropyl alcohol could most easily be separated by use of magnetism filtration distillation

Explanation:

Sand is insoluble in isopropyl alcohol and is a solid - like substance while isopropyl alcohol is a liquid. Filtration is a separation technique used to separate a solid - liquid mixture where the solid is insoluble in the liquid. Sand can be retained on the filter paper while isopropyl alcohol will pass through as the filtrate. Magnetism is not applicable as neither sand nor isopropyl alcohol is magnetic. Distillation is used for separating mixtures based on differences in boiling points, which is not the most straightforward method here as sand is a non - volatile solid and isopropyl alcohol is a volatile liquid, and filtration is simpler for this solid - liquid separation.
