Thanks to the students who sent me these cool links – I won’t name names in case that would cause embarrassment, but much appreciated and thank you for sharing!

Polyatomic Ion Quizlet: Flash Cards

Youtube song about Polyatomic Ions: Hooray!

This is the lyrics:
Let’s get down to business with ammonium N H 4 Positive it’s the only one. Nitrite and nitrate are 2 and 3 and they’re both negative. If I pass this quiz, I will live. Next comes the Chlorines C L O, 2 3 and 4, don’t forget their negative just like the ones before so are hydroxide, cyanide, and permangante OH, CN, MnO 4. Bisulfate is H S O 4 Dihydrogen phosphate, H 2 P O 4, bicarbonate is H C O 3. Accetate is the longest C 2 H 3 O 2. Now it’s time to learn the ones that are minus two carbonate Co3 -2. Sulfite and fate are three and four. Chromate is Cr O 4. Dichromate is Cr 2 O 7. Now we’re almost through. We’ve got three to go. peroxide has two atoms and their both O. Hydrogen phosphate is the last one and it’s H PO 4 oh and phosphate is PO 4, three minus!

Recap of transition metal naming. Introduced polyatomic ions. Just like vocabulary in a foreign language, these need to be memorized. Click on the link below for the table of ions that need to be memorized for this year.

Answers to Ksp Practice Sheet

Pardon the formatting – blogs aren’t really set up for Chemistry.

1a. Ksp = [Fe³⁺][OH^-]³
1b. Ksp = [Ca²⁺]³[AsO₄^3-]²
2. Ksp = 1.2 x 10^-7
3. Solubility = 3.0 x 10^-5 mol/L
4. Solubility = .27g MgCO₃/L
5. [Hg₂²⁺] = 5.0 x 10^-8 M
6a. Yes, PPT (Q = 4.5 x 10^-6)
6b. Yes, PPT (Q = 4.9 x 10^-5)
7. No PPT (Q = 2.5 x 10^-12)
8. Yes, PPT (Q = 3.7 x 10^-5)

Precipitate Lab Sets

Here are the chemicals for the lab tomorrow. You need to split them up into the ions they are composed of. For example:

Ba(NO₃)₂ is composed of Ba²⁺ and 2 NO₃^-. Determine the pairs of ions for each chemical so you are prepared to just fill in your data tables and begin working tomorrow.

If this works…here is a map/flowchart for deciding how to name a compound…to get a formula just work backwards.

Naming Review and Study Tips

westchem — Thu, 28 Oct 2010 13:23:27 +0000

Be sure and check out the Helpful Tools and Links page (bottom of right column) – there is a link to an overview of naming rules and organic naming rules there which you may find helpful.

Some general tips:

Make sure you know the rules for each kind of naming (ionic, covalent, acids, organic).
Be able to identify the kind of compound, so you know which set of rules to apply.
Just like learning a new language, practice! practice! practice! is the best way to get good at it. Try extra problems at the end of Chapter 3 (odd answers in back of book), or try a friend’s WebAssign if they have different problems than you do.
The Mr. Guch’s website (on my links page under General) has many practice worksheets with answer keys to use!
