Class Blog 11/4/13

Before Class:

1. First, our homework (Solubility Curve Practice Problems Worksheet) was checked in for points.

2. Next, we picked up three handouts. One was a packet titled “Molarity: How can the concentration of a solution be expressed quantitatively?” (can be found here), and a two part worksheet simply titled “Molarity” (can be found here)

During Class:

1. We started class by reviewing each question on the Web Assign which was due Sunday night at 11:59 PM. The Web Assign didn’t show us whether or not we got the answer wrong, so don’t freak out!

-Some main ideas to pull from the Web Assign: whenever a compound is insoluble, it will create a precipitate. The inverse is also true; if a compound is soluble, then a precipitate will not form.

-Our textbook has very helpful examples regarding the Web Assign questions.

-Also remember that it is more important to learn the big idea of a lesson even if it means losing a couple points here and there. Don’t get hung up by one bad grade!

2. Next we reviewed our homework that was due today (Solubility Curve Wksht)

-Answer key can be found here.

3. After this, we worked with partner on the Molarity packet up to the first stop sign.

-We ended class by going over the answers quickly
