- Today we went over the Ksp packet in class and Mrs. Friedmann reviewed how to do each type of problem. She also added some notes to the last page of the packet. In addition Mrs. Friedmann told us about the upcoming science contest that we could participate in. Lastly we took some notes about solving common ion problems.
Science Contest:
- This is the same contest that some of you may have participated in groups last year. And although there will be no extra credit given for attending the event, it will still be a great experience that is worth much more than extra credit points!!!
Ksp Packet Review...
- Mrs. Friedmann went over how to do each problem in the packet, such as calculating concentrations, ksp, or S (solubility). All of these problems involve using the ICE methods and finding out the Ksp expression which is similar to finding Keg. This packet with the answers is posted on moodle.
Common Ice Problems...
- This method is used to solve solubility of substances in another solution (not in water like the ones in the Ksp packet). This is important because instead of starting of with 0 on the product side, you start of with a certain concentration since the we are dealing with a certain solution not just plain water.
Here are the notes...
Homework...
-Answer this problem: How many grams of CaSO4 are formed when 20mL of 0.010M Na2SO4 are added to 100mL of 0.001M CaCl2.
