solution 
A homogeneous mixture of two or more solutes dissolve in solute
homogeneous 
uniform composition and properties throughout
solute 
the substance that is dissolved
solvent 
the substance that does the dissolving
saturated 
one in which no more solute will dissolve under the existing conditions of temperature and pressure
unsaturated 
contains less than quantity of solute needed to saturate it under the existing conditions
supersaturated 
contains more solute than a saturated solution could normally hold for existing set of conditions
concentrated 
large proportion of solute and the dissolve particles are closer together than in a dilute solution
dilute 
small proportion of solute and the dissolved particles are far apart
mixture 
Two or more substances that physically combined with a variable ratio
solubility 
measure of how much solute can dissolve in a particular amount of solvent - 100g of solvent at a given temperature
miscible 
two liquids mix together in any ratio to form a solution
electrolyte 
a substance, that when dissolved in water produces ions
strong electrolyte 
substances where all of the particles dissolved exist as ions
weak electrolyte 
exist in solution mainly in molecular form
non-electrolyte 
substances that remain as molecules in solution. Do not undergo ionisation
dissociation 
process that occurs when ionic compounds, are added to water. Ions in lattice separate and ionic bond is broken and aqueous ions are produced.
ionisation 
process that occurs when covalent molecular substances are added to water. They react with water to produce ions
spectator ion 
ions present in solutions, that do not take part in the reaction
ionic equation 
shows the species that are reacting and products produced
precipitate 
insoluble solids - sometimes when two solutions containing soluble salts are mixed
reagent 
a compound or mixture added to a system to trigger/start a chemical reaction - a catalyst
