Thurs-Day 2
Physics - took part I of the Work and Energy unit exam.
AP Chem- did the remaining 5 and 6 electron-domain types of molecules and ions, emphasizing placement of any and all LONE PAIRS of electrons on the EQUATORIAL triangular plane in the 5 electron domain species.
We had to readjust our redox titration lab because the equivalence points had been reached after the addition of a mere 6 mL of titrant. We could have titrated MORE bleach solution or less dilute bleach solution but we decided that it would be easier or more practical to do a 1:5 dilution of the titrant, bringing our thiosulfate concentration to about .025M.
