Solutions are homogeneous mixtures made up of very small pariticles that are in fact individual molecules, atoms, or ions.
Solute- The substance in a solution which is considered to be dissolved.
Solvent- The substance in which the solute is dissolved. (an aqueous solution is one in which water is the solvent)
Saturated Solution- is a solution that has dissolved in it all the solute that it can normally hold at given conditions.
Unsaturated Solution- is a soluition that contains less solute than it can hold at given conditions.(it has room for more solute to be dissolved)
Supersaturated Solution- is a solution under special conditions that can hold more solute than is present in their normal saturated solution. It occurs when a saturated solution at a high temperature is allowed to cool gradually while it is undisturbed
Molarity
Molarity is the concentration of a substance per unit of volume.
Molarity=M= moles of solute/ liters of solution
Molality
Molality is the moles of solute per every kilogram of solvent.
Molality=m= moles of solute/kilogram of solvent
