Learning Objectives
Sect 1-8
*Identify that neutralization requires [H3O+] = [OH-], as opposed to requiring pH = 7, based on the
dependence of Kw on temperature.
*Use proton transfer to identify compounds as Bronsted-Lowry acids, bases, or neither.
*Identify conjugate acid-base pairs.
*Translate an observed chemical change in to a balanced chemical equation (molecule, ionic, net ionic).
*Draw and/or interpret representation of solutions that show the interactions between solute and
solvent.
*Draw and/or interpret representations that link the concept of molarity with particle views of solutions.
*Determine the effects of manipulations on Q or K.
*Given K, determine which chemical species will have very large versus very small concentrations at
equilibrium.
*Use Ka or Kb values to infer relative strength of acid or base.
*Use particulate representations of acids and bases (strong, weak, polyprotic) to explain which species
will have very large versus small concentrations at equilibrium.
*Draw models illustrating the relative amounts of species in solutions of one or more acid or base (only
acids or only bases … mixtures of acids and bases is covered in the next chapter).
*Perform calculations relating pH, pOH, pKa, pKb, Ka, Kb, Kw, [H3O+], [OH-], [HA], [B], % ionization in
solutions containing one or more acid or one or more base.
*Calculate or estimate the pH and/or concentration of all species, in a solution of one strong or weak acid
or base, or a mixture of acids, or a mixture of bases. (the mixtures would contain at least one strong acid
or base).
*Reason about the distinctions between strong and weak acid solutions with similar pH values, including
% ionization of each acid and concentration of each acid.
Sect 9
*Predict whether an aqueous solution of a salt will be acidic, basic, or neutral.
*Rank acidity (or pH) of chemicals listed (acids, bases, and salts) based on the Ka or Kb of the associated
cations and anions and/or their conjugates.
*Calculate the pH of solutions containing a given concentration of salt (only if it only contains one ion that
effects pH).
Sect 10
*Predict the relative strength of a series of acids from their molecular structures:
-trends in atomic properties (IE, EA, Radius, Reactivity) based on location on the periodic table
and/or the shell model.
-relationships between the structural features of polar molecules and the forces of attraction
between particles.
