Additional Note:
- Be sure to use the 5% rule to validate your assumption each time you ignore the +X or –X when dealing with the concentrations. There were two other times in this problem where we should have used the 5% rule, but we omitted them for the sake of time.

Corrections to the Video:
- @ 5:12 ; “solving for x” – it says to take the log and square that number, you are supposed to take the log and then take the square root of that number.

- PART B ; the first reaction with hydroxide and acetic acid has equilibrium arrows; this reaction should just be written with a forward arrow.

- @ 16:16 ; “the pOH is the negative log of the hydronium ion concentration” – I misspoke, the board is correct, and the pOH is the negative log of the hydroxide (not hydronium) ion concentration
