HUMOR: ON
THE FUN SIDE
1. “Mathematicians have problems, but chemists have solutions.” [Students could make bumper stickers.]
2. ÊC 7 2 NaCl(aq) [Saline, saline, over the seven C’s]
3. Then there are the witches from William Shakespeare’s Macbeth: “Double, double, toil and trouble,
Fire burn and cauldron bubble.”  Even the great bard of the English language was into making solutions!
4. A modern young man thought he’d boobed When the milk he had ordered came tubed Instead of “One liter”
The package read (neater) “Contents are one dm cubed.” (CHEM 13 NEWS, September 1978, p. 25)
5. a. Question: How do you make antifreeze? Answer: Hide her scarf and mittens.
b. Solute is what you give a general.  (CHEM 13 NEWS, December 1976, p. 1123)
6. Another message on a bumper sticker: Chemists have solutions...
 7. Word Search (see Appendix for master copy)

                                           Words about the concepts in this module can be obtained from the clues given. Find these words in the block of letters:

                                                                    6. Type of unstable solution that has a higher concentration of solute than normal at a given temperature.
                                                                    7. Extent to which a substance dissolves in a fixed volume or mass of a solvent at a given temperature.
                                                                    8. Adjective describing a solution in which water is the solvent.
                                                                    9. That solution component into which the solutes are considered to have dissolved; the component that is present as
                                                                        the continuous phase.
                                                                    10. Ratio of moles of one component divided by the total moles of all solution components, including the solvent. (two
