indicator
substance that changes color in an acid or base
strong acid
dissociates completely in water to produce a lot of hydrogen ions
weak acid
releases only a few hydrogen ions in solution
strong base
dissociates completely in water to produce a lot of hydroxide ions
weak base
produces only a few hydroxide ions in solution
neutralization
chemical reaction of an acid and a base producing water and a salt.
salt
ionic compound made from the neutralization of an acid with a base
electrolytes
solutions that are capable of conducting an electrical current.
dissociation
ionic compound breaks apart in water to form positive and negative ions
solubility
quantity of a substance that dissolves in a given amount of a solvent
solute
substance that is being dissolved
solvent
substance that does the dissolving
supersaturated solution
solution that contains more solute than it is suppose to hold
saturated solution
solution that cannot dissolve any more solute
unsaturated solution
solution that can still dissolve more solute
polar
a molecule with a positive side and negative side
nonpolar
molecule that has no positive or negative side
like dissolves like
polar solvents dissolve only polar solutes and non polar solvents dissolve only non polar solutes
insoluble
substance that will not dissolve in a solvent
pH
scale that rates the strengths of acids and bases from 0 to 14
