When a mixture of salt and water freeze, the two substances will not separate. The mixture will just become frozen salt water.
A possible hypothesis could be: "If salt is mixed with water and the solution is frozen, then the salt will not separate from the water, as both salt and water will freeze together into a solid."
Salt lowers the melting or freezing point of water. The effect is termed 'freezing point depression'. Therefore frozen salt water melts faster and remain melted for long.
Use filtration to separate the sand from the water and salt. Then use evaporation to separate the salt from the water. Use distillation to evaporate the water, leaving the salt behind. Then use filtration to separate the remaining sand from the salt.
By evaporation of the water and crystallization of the salt.
You can separate salt and water by using the process of evaporation. Simply heat the mixture until the water evaporates, leaving the salt behind. This method works because salt does not evaporate with the water.
no
yes

No, not from the frozen state. If a saline solution (dissolved salt in water) is gently heated, the water will evaporate, leaving salt crystals behind. If the water vapour is captured and condensed, the result is drinking water.
A hot plate will separate salt water.
The freezing point of salted water is lower compared with the freezing point of pure water. So when melting frozen salt water is colder.
Evaporate the water.

no, the salt wont go away it will just be inside the frozen water i don't think salt freezes though.
In order to separate salt from water, you need to boil the water. Once all of the water has evaporated, the salt will be at the bottom of the container the water was boiled in.
No, it cannot separate salt from a salt solution. This is because salt is soluble in water.
To separate salt water into salt and fresh water you can use:a distillation apparatus, ora reverse osmosis process
