| Goal
I. Understand the terms used to describe a solution
and the characteristics of its components. |
Objectives: To meet the requirements
of Goal I, you must be able to:
- distinguish
between the
solution, solvent, solute; and then determine
which component of a
solution is the solvent and which is the solute;
- explain
the term solubility
(p. 76), concentrated and dilute (pp. 122-123)
used to describe solutions;
- explain
the term electrolyte and distinguish between strong, weak
and nonelectrolytes in terms of:
- the proportion of solute that
forms ions, and
- the ability
of a solution to conduct an electric current;
- classify
an electrolyte as an acid, base or a salt from its formula;
- use Table
4.2 to classify acids and bases as strong
or weak;
- use Table
4.1 to classify an ionic compound as soluble,
slightly insoluble or insoluble;
- write equations
representing the ionization of strong and weak acids and
bases in water, and for the dissociation of soluble salts
in water.[Top]
| Goal II.
Use tabulated data to predict products and write equations
for some commonly encountered reactions. |
Objectives: To meet the requirements
of Goal II, you must be able to:
- predict
whether a precipitate will form when solutions
of salts are mixed; then write
molecular, complete ionic and net ionic equations for
any reaction which occurs including acid-base reactions, proton-transfer reactions, redox reactions and oxidation numbers (pp 145-163) .

| Goal III.
Use Standard quantitative concentration units; solve
stoichiometric problems involving reagents in solution. |
Objectives: To meet the requirements
of Goal III, you must be able to:
- calculate moles or grams of solute, volume of solution, molarity,
given two of the three quantities;
- solve problems concerning the dilution of a solution with water;
- explain
the terms titration, standard solution (read Lab Manual expt. 9),
indicator;
- explain
the significance of the end point in a titration and how
it is determined;
- calculate the quantity of any other reactant or product given the
quantity of any reactant or product in a titration (in
grams, moles or concentration and volume of solution);
- solve
titration problems. [Top]
