Solutions

When you have added as much solute as can dissolve in the solvent, the solution is called:

• concentrated

• supersaturated

• saturated

• unsaturated

Answer explanation

Once the solvent is saturated, no more solute will dissolve. Any extra solute will just sink to the bottom.

To make a supersaturated solution you have to heat up the solution and cool it down gently--its is not easy to do!

• Suspension
• Colloid
