True/False: An unsaturated solution is one which more solute can be added and dissolved.

A

TRUE

17
Q

What is the saturation point?

A

When no more solute can be dissolved

18
Q

What 4 things affect solubility and rate of dissolving?

A

1) Type of solute and solvent
2) Temperature
3) Particle size
4) Agitation

19
Q

What is the Particle Model of Matter?

A

1) All matter is made up if tiny particles. Solids have more than gasses and liquids
2) The particles are ALWAYS moving
3) Particles may be attracted to each other or bonded together
4) There are spaces between the particles
