A solution is made when a is dissolved in a liquid called a solvent, usually water.
If the solute is white (e.g. sodium chloride) then the solution is .
This is because the individual particles in the sodium chloride crystals break apart and spread out through the .
If the solute is coloured (e.g. copper sulfate) then the solution will have a colour.
As with the white solute, the particles are now too small to see, and are evenly out.
Adding more water to copper sulfate solution will make it a shade of blue, because the blue particles will now be apart.
This is proof that both the solute and solvent are made from tiny .
