LEARNING OBJECTIVES

Describe properties of aqueous solutions of acids and bases.
Account for differences between acids and bases in terms of the Arrhenius model.
Use the Bronsted-Lowry model of acids and bases to identify the proton donor, proton acceptor, conjugate acid and conjugate base in a given equation.
Describe strength of weak acids and bases in terms of the extent to which they compete with water for H+ ions.
Distinguish “concentrated” from “strong” and “dilute” from “weak” as these terms are used to describe acids and bases.
Given the mass (or number of moles) of a known strong acid or strong base and the total volume of solution, calculate the [H3O+] and [OH–].
Describe indicators as weak acid/base mixtures whose acidic and basic forms have different colors.
Given the volume and concentration of known acid (or base) used to titrate a base (or acid), calculate the concentration of the unknown solution.
Recognize that pH is a way of describing the [H3O+] of solutions using a logarithmic scale. Given the [H3O +] or pH, calculate the other.
Identify the endpoint of a titration as the point at which the rate of change of [H3O+] is greatest.
