How does evaporation change the concentration of a solvent in a solution?

Answer 1

yes salt concentration increases because the ratio of water to salt changes as the water evaporates under heat.

at the beginning levels are normal but as there is less water it will be more salt.

look at it this way:

beginning- if you have a cup of water and one teaspoon of salt its even distributed

end- now if you have half a cup of water and one tablespoon of salt, you ll notice its the same amount of salt but the second solution contains much more.

Answer 2

As you evaporate water from salty water, the remaining water will have a higher concentration of salt, and eventually salt crystals form when the salt concentration exceeds the solubility of the salt, and beyond that, if the water continues to evaporate, eventually you will just have salt left.

Answer 3

As evaporation proceeds there is less and less water left and the concentration of salts increases until the salt concentration reaches the saturation point. After this as evaporation continues the salts come out of solution and begin to form salt crystals.

Answer 4

the water evaporates and the salt stays!! :)

we did it so many times in science last year....

Answer 5

it will increase.
