Q2: Week 4 – 12/6 – 12/10
Jump to: Tuesday, Wednesday, Thursday, Friday
12/6 – Monday – A Day – A Day – 2/3a Lab, 4
a) To review the the TUMS Lab design of back titrations and solutions needed.
b) To review the Standardization of NaOH with KHP.
c) To complete the standardization of NaOH with KHP.
Period 2/3:
1. Complete the review of the design of the TUMS Lab
2. Complete the review of the Standardization of NaOH.
3. The Standardization of NaOH with KHP Titration.
Period 4:
1. Complete the review of the Standardization of NaOH.
2. The Standardization of NaOH with KHP Titration.
Today’s Notes:
____________________
12/06 – Monday Homework: –
1. Please continue with the formal write-up of the TUMs lab. You should be able to get farther with the procedure as everyone was able Standardize the Strong Base to verify the strength of the base.
I made a 0.50 M NaOH solution but one group today found it was 0.482 M which makes sense as the base solution is very reactive and deliquescent.
End of Monday!!!
Solution Review for the Tums lab:

12/8 – Wednesday – A Day – A Day – 2/3a Lab, 4
a) To calculate the milligrams of calcium carbonate in a tablet of Tum
b) To identify and explain the errors in Lab 13 – Tums Lab
c) T0 begin the design of the Lab 14 – Determination of aspirin in a Bayer Tablet.
Period 2/3:
1. Tums Lab Calculations Review
2. Tums Labs Lab error analysis
3. Aleve Form – This is based on a Back Titration (just like you would to for the next Lab).
Period 4:
1. Tums Labs Lab error analysis
2. Aleve Form – This is based on a Back Titration (just like you would to for the next Lab).
End of Thursday….
