Q2: Week 2 – 11/22 – 11/23
Jump to: Tuesday, Wednesday, Thursday, Friday
11/22 – Monday – B Day – 2, 3b/4 Lab
a) To review the weak acid /strong base Titration
b) To identify buffer solutions
c) To use the Henderson – Hasselbach to answer point 3 questions
Period 2: Collect Titration quiz (from the form).
1. Review Lab 11 and the homework form (another weak acid/base titration).
2. Review Past 2 Acid Base Homeworks – YOU MUST BE ABLE TO IDENTIFY which Points on the titration graph ( 1 – 5) you are working with.

Period 3/4: Collect Titration quiz (from the form).
1. Same as above
Today’s Notes:
From this weekends homework:
Strong Acid Strong Base ~Lab 10 |
pH = 7 @ equivalence | only spectators that DO NOT ionize water |
Weak Acid Strong Base ~Lab 11, |
pH >7 @ equivalence | Conjugate Base produced reacts with water to produce OH- |
Strong Acid Weak Base ~Last nights HW |
pH <7 @ equivalence | Conjugate Acid produced reacts with water to produce H3O+ |

The Blood buffers the blood pH so that you survive!!! There are so many organic molecules that have acidic or basic properties that would cause death in our aqueous plasma (fluid part) of our blood. The main buffer in our blood that prevents large pH changes if the following conjugate acid base pair: Conjugate Acid Conjugate Base

Sodium Carbonate / HCl (weak base / strong acid Titration): The blood buffer!
End Of Thursday!

11/23 – Tuesday – A Day – 2/3a Lab, 4
a) To review a weak base strong acid prediction titration curve of 5 points.
b) To perform a weak base strong acid titration (Lab 12)
Period 2/3:
If Last nights homework was a disaster please do not hand it in. I will have everyone do another prediction graph next week . Please review the key when you get a chance. The titration we did today we will do in class next Monday!
