First Aqueous Solutions notes

We fit a lot of information into one set of notes, but yet I don't feel that overwhelmed. We learned % mass, molarity and concentration of ions

Here is a link to a crash course solution that I thought helped.

Some random things to remember that i got down that might now be to the main notes:(please correct  me if I don't have certain details correct)

  • If a substance on a solubility curve has a negative slope, it is most likely a gas.
  • Hydrogen bonds with only certain substances when in a long chain. the pneumonic for those substances is "phone call" or spelled F.O.N. Cl*. (the chlorine is only if it is terminal meaning on the end of the chain)
  • Like dissolves like, polar dissolves polar, non-polar dissolves non-polar, ionic dissolves similarly to polar substances.
  • When stating the answer in concentration of ions problems, state the charge in your answer if it is needed.
  • (Volume of L)(Mol/L)=moles
  • i(supposed to be cursive) is the Van't Hoff factor, which is the number of ions a substance will break apart into.
  • Van't Hoff affects the melting/boiling/freezing point of solutions.
  • Van't Hoff of covalent compounds is 0 because they do not ionize.
  • you cannot have a Van't Hoff of zero, it starts at one.
That turned into a lot, but there it is.

Have a wonderful night and good luck with the studying

  1. Thank you for the extra side notes. Most of them are quite helpful. I also agree with you that there has been a substantial amount of information. However, it's been a bit more difficult for me because I missed to days of school on a trip to Washington D.C.

  2. I felt very overwhelmed by all of the notes and confusion that she gave us all in one day. I'm glad though some people weren't very confused. Thanks for explaining the notes though.

  3. Thanks for the extra notes, I know where I will come in the future when I need help with notes or if I have trouble copying down everything off of her slides. It's a fast paced class and sometimes there is an overwhelming influx of information, so I'm glad to have someone like you in the class to help me out.
