Optional Extra Study |
PLEASE NOTE THAT THE INSTRUCTIONS START AT THE BOTTOM OF THIS PAGE AND WORK UPWARDS
- PRINTOUTS OF ALL MATERIAL WAS DISTRIBUTED FRIDAY BEFORE CLOSURE.
Friday April 3rd - Day 40
Thursday April 2nd - Day 39
- carefully read section 8 in the nomenclature
note
- THIS IS THE MOST DIFFICULT SECTION. THE PREFIX METHOD IS USED
INCONSISTENTLY AND OFTEN INCORRECTLY. IN ORDER TO ACHIEVE SUCCESS,
COMPARISON WITH OTHER FORMULA THAT CONTAIN DIFFERENT CATION OXIDATION
STATES IS ESSENTIAL. THE USE OF PREFIX MUST BE ABLE TO DISTINQUISH
THE DIFFERENCE BETWEEN FORMULA, USUALLY ADDED TO THE ANION, BUT OCCASSIONALLY
ADDED TO THE CATION, RARELY ADDED TO BOTH!
- attempt the first section in worksheet
#6 & #7(answers) and check your
answers
- complete reading section 9 and 10 in the nomenclature
note
Wednesday April 1st - Day 38
Tuesday March 31st - Day 36
Monday March 30th - Day 35
Friday March 27th - Day 34
Thursday March 26th - Day 33
- review what you have learned yesterday
- carefully read through section #6 from the nomenclature
note
- try to memorize the BIG
SEVEN summary using the blank
copy or just a blank piece of paper (should involve writing and checking)
- short focused sessions should be more productive than draw out work periods
Wednesday March 25th - Day 32
- review what you have learned yesterday
- try to memorize the OUS/IC
vs I.U.P.A.C. summary using the blank
copy or a folded blank piece of paper (should involve writing and checking)
- short focused sessions should be more productive than draw out work periods
Tuesday March 24th - Day 31
- review what you have learned yesterday
- carefully read section 5 of the nomenclature
note
- KEY IDEA: Polyvalent elements have more than one oxidation state and that
oxidation state must be stated in the name in order to avoid confusion with
more than one possible formula. There are two ways of doing this, the
more reliable I.U.P.A.C. method (can be used for all polyvalent cations) and
the older less reliable OUS/IC method (can be used for only selected cations
- limited use)
- please notice that some memorization work will be involved here - see OUS/IC
vs I.U.P.A.C. summary (blank
copy)
- please note that only a few elements have an OUS/IC name and that for compounds
containing these elements, two names should be written, one using the older
OUS/IC method and a second name using the more reliable I.U.P.A.C. method
- complete worksheet #2 and check the answers
- please use the OUS/IC
vs I.U.P.A.C. summary to get through this sheet
Monday March 23rd - Day 30
