1.4- know what is meant by the terms: Solvent, solute, solution and saturated solution

When a solid dissolves in a liquid:

-        The substance that dissolves is called the solute

-        The liquid it dissolves in is called the solvent

-        The liquid formed is a solution

-        A Saturated solution is one in which no more solute can be dissolved- contains as much dissolved solid as possible at a particular temperature. There must be some undissolved solute present.

When you make a solution, the attractive forces between the particles in the solute are being broken, and new ones being formed between the solvent particles and solute particles. Whether a particular solid is soluble in a solvent is reliant on whether or not the new forces of attraction are strong enough to overcome the old ones- therefore some solids can be insoluble.
