Why does adding salt help water boil more quickly?
No, adding salt does not make water boil more quickly. The colligative properties of water talk about freezing point depression and boiling point elevation. Water will reach a higher temperature before it boils when it contains salt (or any other dissolved substance). Nucleation is a reasonable point, though. In reality, it’s probably going to be hard to detect much of a difference. If you’re cooking at high altitudes and you add salt to try to make the water boil faster, you’re working against yourself.
