|Why does water boil quicker when you add salt?
Salt should actually delay boiling in water by raising the water's boiling temperature. The water simply won't boil until its temperature reaches a certain value and that requires heat. There isn't any trick that will shorten the heating time, except to add chemicals that boil at lower temperatures than water (e.g. alcohol). But sprinkling salt into very hot water may trigger boiling by providing nucleation sites on which the bubbles can begin to form.
