Salt is dissolved in the water so when we heat it the water evaporates leaving salt below. Salt water can't evaporate. However, the water fraction of it can, and often does, but then the salt (Sodium Chloride, NaCl), is left behind. A look at the Utah salt flats shows what it looks like when it's left. This can happen when a large inland sea is then cut off from the sea, and the water is evaporated over time, leaving behind a salt lake. These can then become buried by sediment and become a certain type of rock called "evaporites", so called because the water evaporated and left a mineral 'deposit'.
A lot of the water vapour in the atmosphere is evaporated sea water, and if you watch the evolution of a hurricane for instance, you will see that the system builds over water as it collects water vapour, then dissipates over land.
What else can I help you with?
When sand and water are mixed is it reversible?
yes, just evaporate water and you are left with sand
2 ways to separate a mixture of salt sand and water?
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.
Which progress can be used to separate sand and water?
A simple filter would be suitable for separating sand and water. An alternative would be to evaporate the water, leaving the sand behind.
What is the technique in separating water to sand and table salt?
First decant the water - the sand will be left behind. Then evaporate the water and the salt will be left behind.
How would you separate sand from water as a mixture?
Not sure what is meant by mixtures? But, the sand and water can be heated to evaporate off the water, which can be condensed back into water. This will leave the sand behind.
Does sand water evaporate?
Water from sand is evaporated.
HOW DO YOUSperate sand from water?
let the water evaporate
When sand and water are mixed is it reversible?

How can you separate water from a mixture of sand and water?
You can filter it or evaporate and condense the water
How would you separate this material sand mixed with water?
set the mixture out in the sun and let the water evaporate leaving the sand
Which progress can be used to separate sand and water?

What is the technique in separating water to sand and table salt?
First decant the water - the sand will be left behind. Then evaporate the water and the salt will be left behind.
How could you separate a mixture of sugar and white sand.?
Dissolve the sugar in water and then evaporate the water
How would you separate sand from water as a mixture?
Not sure what is meant by mixtures? But, the sand and water can be heated to evaporate off the water, which can be condensed back into water. This will leave the sand behind.
Can you put sand in a microwave to dry it?
yes, it'll still evaporate the water.
Why is mixing of sand with water a reversible change?
Because - you can simply evaporate the water by heating it, and collect the water in a separate vessel - leaving the dry sand intact.
