Dissolving, Concentration, Evaporation, Crystallization

Dissolving

-Is when particles diffuse through the liquid.

-This is a physical change NOT a chemical change.

For example when something like a sugar cube put in hot water, the particles slowly diffuse through the water. When it completely dissolves there is no solid left. This making the water know a solution.

Concentration

-This happens after dissolving.

If there is one sugar cube in a glass of hot water and it dissolves it is less concentrated. Or the solution has more dilute. But if there are three sugar cubes dissolved in a glass of water the solution has a higher concentration of solute.

Evaporation and Crystallization

Salt water can evaporate with time making the salt solution more concentrated. Eventually all the water will evaporate crystals of salt will begin to form called crystallization.

Distillation

The water evaporates, but the salt does not. On the side arm water vapours start to condense. This Fractional Distillation is good for separating solutions and recovering the liquid. There are different separation methods like evaporation or filtering.
