Unit 5 Solutions Acids and Bases

A homogeneous mixture in which the minor component (Solute) is uniformly distributed within the major component (solvent)

• solution

• solubility

• Acid

• Base

A substance doing the dissolving, usually the part of a solution present in the larger amount

• solvent

• solute

• solution

• solubility

a substance being dissolved, usually the part of the solution in the lesser amount

• solvent

• solute

• solubility

• concentration

the ability of a substance to dissolve in a solvent

• solution

• concentration

• solute

• solubility

a substance that vigorously reacts with most metals to produce hydrogen; it readily conducts electricity; it turns litmus red and has a pH of less than 7; it typically is corrosive or sour-tasting

• acid

• base

• neutral

• solution

a substance that does not react with most metals or readily conduct electricity; it turns litmus blue and has a pH of greater than 7; it typically feels slippery and is bitter-tasting

• acid

• base

• neutral

• solution

a substance that has a pH of 7; water is an example

• acid

• base

• neutral

• concentration

a measure of how acidic or basic a solution is; the low it is the more acidic, the higher the more basic

• concentration

• pH

• conductivity

• solubility curve

indicator that turns red in the presence of an acid and blue in the presence of a base

• solvent

• solute

• litmus

• temperature

a substance such as litmus or phenophthalen that indicates if a substance is an acid or a base by means of a color change

• solvent

• agitation

• concentration

• indicator
