How does salt help boil water and help ice freeze? - can i use ice to freeze my gential warts
My grandmother always has a pinch of salt in a pot with boiling water so that it achieves a quicker. But to the ice with salt to freeze the ice quickly. As at different temperatures, cold water is no help to cool the heat, and the ice faster? Thank you in advance:)

It's easy. When salt dissolves in water, the salt ions from the water molecules to keep the molecules come apart easily.
So, if the water to boil, the individual molecules, which is heated, the attraction of neighboring molecules deficiency, easily removed from the surface of the water vapor (gas). It therefore requires less heat and cooking is performed at a lower temperature.
Moreover, when the water cools down, like in the gel, the individual molecules, the attractive forces of neighboring molecules are not lacking easily be able to produce compounds in a crystal (solid) state. Therefore require more cooling and refrigeration equipment is achieved at a lower temperature. Now for ice cream, you have very cold water. This is by the addition of salt in water, then freeze achieved.
Note that the boiling and freezing point is lowered by the addition of salt.
Her grandmother is a wise woman!
Well said, unfortunately, that is the grandfather of a mistake to think that, with salt in boiling water. Prevented in fact, bring the water to a boil.
I refer to the Wikipedia page.

It gives you an equation such as temperature changes) with increasing molality (m. By adding more salt to pure water, the temperature can be increased one degree per couple and can therefore slow cooker.
Remember that water boils at 100 degrees. C, then add the salt, increase the temperature.
______________________________
even if you take a bucket with ice and a little salt to the ice to melt. But (the melted some of them) refreeze. However, the addition of salt the same thing with ice. The water temperature rises, so does not freeze. This is the reason for the salt on the roads in winter.
Good luck.
