Week of 1/30

Monday:

Today we started with a quick review of what a buffer is and how to identify one.

Tuesday:

Today we started with the titration simulation so that you could see that not all equivalence points will be at a pH of 7.  We talked about why that happens for weak acids and bases (its because of their conjugate that is present at the equivalence point).  We identified the buffering region and then you all spent the rest of class working in groups drawing molecular level pics of 4 parts along a titration curve on big paper.

Test on Acids/Bases: Monday

Wednesday:

Today we worked titration problems – how to find pH at equivalence point, buffer region, etc.

Thursday:

Today we did the indicator lab. HW was a google classroom assignment on the subject.

Friday:

No school, end of quarter grading day.
