Apologia: Chemistry, Nomenclature

The class took notes on the basics of chemical nomenclature: binary ionic compounds, covalent molecules, polyatomic ions, the Stock system, and acid nomenclature.  The class took notes before beginning an ion lab.  (They also collected data for the Specific Heat of Metals lab we will debrief next week, since there was not enough time this week.) the ion lab is pretty simple; I made 1M solutions with CaCl2, CuSO4, NH4OH, AgCl,  and MgSO4.  I labeled each vial by either its cation or anion.  The lab requires combining the chemicals into reaction plates and is similar to the 'Forming and Naming Ions' lab below.  Once the class recorded their observations in a data table.  Any combinations which demonstrated a reaction had to be named.  After this introductory lab, the kids worked to build ions working through the data sheet which is part of 'Putting the Ions in Their Hands' or 'Ionic Formula Writing'.  After finishing the data sheets and reviewing their answers, the kids tackled their ion lab to see if they could use the paper ions to name their compounds.  Lastly was a brief lesson explaining the notes they had copied earlier.  The kids are doing a mini-project developed by Dr. Bob Warburton researching chemical compounds in common substances.  Next week, the class  will do a lab with CaCl2, NaHCO3, and phenol red.  Below are most of the resources for this week's nomenclature lesson.  Next week, the group will do the thermochemistry labs.

Acid Naming (Bridge on the River Quai)
Acids there are two kinds of them
Acids there are two kinds of them
Binary you add a hydro
Put on an ic and add an acid
And you're done, done, done.

Acids there are two kinds of them
Acids there are two kinds of them
Ternary if it's ite make it out
If it's ate make it ic, add an acid
And you're done, done, done, done.

And then there's oxygen if there's two less of them
Hypo is what we call it then
Too many o makes it per you know
One less O and it's ite
And that's no fright
And we're done, done, done, done!
