How can you easily decrease the concentration of a solid solute in an aqueous solution?

[j2buttonsw]

I don't understand "solid solute": was it a solid which is soluble (I guess so as it is a solute)? To decrease the concentration (mass per volume) add more water. If it was 1 g/L and you add a further litre of water the concentration decreases to 0.5 g/L (equivalent of 1 g/2L).

Add more solvent.

If it's an aqueous solution the solvent would be water.

add water....

You could also cool it below its saturation point and the excess will crystallise out.

Add more liquid.
