Fri-Day 1
Chem 4/5 - quantitatively contrasted the effect on pH of adding acid to a non-buffer vs. a buffer.
Emphasized importance of drawing and writing reacting species.
Used pH limits of a given buffer to appropriately choose a pair of conjugates for a desired pH buffer.
Quantitatively determined masses or vol/M of required conjugates - related to actually physically gathering these quantities - easier said than done (hydrated salts, solutions vs. pure acids).
Chem 8 - up to quantitative effects of adding acid to buffer.
APB - derived series, parallel, and combination resistor circuits. Explained same potential difference across each resistor in parallel, different potential difference across resistor in series.
In lab, practiced operating with digital multimeters; formally demo on Monday.
