Aqueous Solutions Retake

Thank the Lord that we had a retake... My grade may or may not have been disgraceful. So I was able regain my family's honor by getting a good(hehe you guys don't know this but i'm in computer apps class typing this and the keyboard doesn't like to type the letters "D" and "T" so when I typed the word good it left out the d which left the word as goo... I'm sorry I'm a dork an though that was funny)grade on the retake. My grade is not in a deep whole now guys don't worry.

More Aqueous Solutions Notes

The next step in aqueous solutions is learning how to integrate what we learned into stoichiometry. It's pretty much the same systematic type of math as the stoic unit but with another added conversion on there. I personally like stoichiometry, but I'm a dork so that could be why. 

Here is an example of a question that i took in m notes. The math is no that bad but there are many rooms for mistakes. 

Good luck, and successful studying.

Murder Molarity Lab

This was a pretty rad lab. Our good friend Mrs. Scarlet was murdered and as a forensic scientist it was our job to figure out who was the killer. First, we  had to figure out what the murder weapon was by undergoing a reaction between the unknown substance that killed Mrs. Scarlett and Na2CO3. The end result of this reaction clears up the mystery of the murder weapon. If the reaction formed a precipitate then we knew that the murder weapon was AgNO3, but if it did not form a precipitate then the murder weapon is KI. The reaction formed .094g of precipitate so we know he murder weapon was AgNO3. To find out who the murderer was we needed to find the molarity of the substance which turned out to be .227 which told us the murderer was professor plum. 

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

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
