Please make sure you remember to wear close-toed shoes and to not wear your contact lenses.

Labs start on tuesday of next week.Today we learnt how to use the pH meter and tested various samples to calculate pOH, H+ and OH -.....I assigned the side of the handout...more Ka, Kb calculations Chem 111We did not have class today because of the assembly on Right to Play-

You worked with a partner on 15 for the last part of the class. From your text please do the following: p 327 #3,4 and p 328 #5,6 and p 298-299 17,19

Today you will work with Ka and Kb calculations and do an in class assignment to pass in on 19.3. Homework: p 611 #24 to 27 p604 #17 to 21 In class you worked on the side part of the handout #7,10, 8 (notes) for MR and BC Chem 122-Today I overviewed titration with you and then you started some group work(77) with amphiprotic and the acid/base table. You received the pre-lab handout. this needs to be completely attempted for tuesday as we will start our first set of labs. We also went over the Ka, Kb. I assigned 8, 9, 12 from the side of the green sheet on Ka and Kb. I went over a pre-lab/lab information. Remember no contact lenses, nylons or open toed shoes on wednesday as we will start labs Chem 111-Today we went over the calculation for finding mass from moles.
