How do you separate salt from grit salt?
One way to separate salt from grit salt is through the process of dissolving and filtering. By adding water to the mixture, the salt will dissolve while the grit remains as solid particles. The solution can then be filtered, leaving behind the grit salt in the filter while the salt remains in the filtered liquid.

Why do we grit roads?
There are two reasons: 1) adding grit to the road helps to improve the tyres' grip on the icy surface. 2) the grit contains salt and that lowers the freezing point of water, so it helps prevent ice forming.
What happens when lorries spread grit on the road?
Grit is spread on the road when grit spreaders do this. They do this in anticipation of Ice forming on the roads. Salts mixed in with the grit which assists in tyre grip will help dissolve the ice
Would a frozen road that has been gritted freeze again?
Short answer yes. Long answer - The salt lowers the temperature at which the mixture freezes. It the temperature were to drop below this the road would freeze again. This temperature varies depending on the concentration of salt. Also if the grit on the road wasn't topped up, it would become diluted and so the temperature required to freeze the road would rise meaning the grit loses it's effectiveness.

How much damage does road salt have on the enviorement?

What happens to the freezing point of pure water when grit is added?
That really depends what you mean by grit. If it's just powdered rock, there is no effect. If you mean rock salt, then the freezing point is reduced because the salt dissolves. The lowest freezing point achievable for salt solution is - 21.1 degrees C.
How did road salt get its name?
