Test Rvw

Good day Chem*Is*Try-ers

The Acid/Base Equilibrium Questions (The review) have been moodlized. [The solutions were scanned, resized and then loaded up to moodle] There are full solutions to the first 8 questions. The 0.150M questions have numeric answers. The acetic acid/NaOH abcd question have partial solutions.

A reminder:
There are basically 3 question types
(1) those involving pH and strong/weak acid/bases & salts
     -weaks are on the p803 chart
     -%ionization fits in this group as well - go back and look at earlier examples
(2) Buffers - weak and its conjugate ion salt -llbm reactions
    -versions of buffer questions - yet again - go back and look at earlier examples
    -buffer upset with strong acid or base
(3) Neutralization questions - those that combine acid and base  - forward reactions
    -pH at equivalence point (all A and B comsumed, becomes pH of salt)
    -one reactant leftover
            -weak leftover, since conjugate ion also produced, becomes a buffer
            -strong leftover, calc pH of leftover strong

Don't forget about the Buffer/Neutralization/Titration questions - all solutions moodlized. Some images may be PDF - requires Adobe Reader to view
The question forum is available as well.
Mind you, some people get up at 5am, so late at night is earlier for early risers.

Finally, there is always the early morning option for those last minute questions. The early riser arrives just shortly after 7am.
