Together we did Unit 4 # 70 odds.  Time was given for #69 evens and for Lab 20G.  In the second half we learned how to find the pH of a weak acid solution, and we read 4.14.  Due Thursday, along with # 69 evens, is # 74-79.

Tuesday, October 19

We started with Lab 20G, finishing the procedure for Parts I to IV.  Do all the Calculations for Parts I through IV, as well as Follow-up Questions # 1-5.  In the second half we took notes on Hydrolysis, we read 4.13, and # 69 (odd letters) and 71 was assigned.  The Unit 4 problems are due Wednesday, but not the lab.
