# Water boiling with salt and without it [closed]

Does 1L of water with salt boil faster or slower than one with the same amount of water but without salt? What I know is that since when you add salt to the water the temperature of boiling increase than the water with salt with take longer.

• The rate of boiling is dependent on heat influx – A.K. Jul 29 '18 at 3:54
• What doe you mean with “boil faster”? E.g. reaching boiling temperature faster starting from room temperature, or evaporating faster to dryness? – user7951 Jul 29 '18 at 16:25

If you are intrested you can calculate the diference in boiling point with the formula $\Delta T = K\ b\ i$, where $i$ is the Van't Hoff factor, (2 for the salt NaCl), and $K$ is the ebuliocopic constant of water ($0.512\ \mathrm{^\circ C\ kg\ mol^{-1}}$), and $b$ is the molality of solution.
