Analytical Chemistry: Preparing for Labs & Grades

Click For Summary

Discussion Overview

The discussion revolves around strategies for preparing for laboratory sessions in an Analytical Chemistry course. Participants share their experiences and seek advice on effective preparation methods, focusing on both practical lab work and understanding theoretical concepts to enhance performance during labs and discussions with teaching assistants (TAs).

Discussion Character

  • Exploratory
  • Homework-related
  • Technical explanation

Main Points Raised

  • One participant emphasizes the importance of knowing the procedures and chemicals involved in the lab to work efficiently and avoid delays due to instrument availability.
  • Another participant mentions successfully finishing lab work early and expresses concern about the TA's questioning, indicating a desire to understand the lab material thoroughly before execution.
  • There is a suggestion that having a datasheet prepared in advance can facilitate data collection during the lab.
  • Some participants note that Analytical Chemistry labs may require more precision and faster execution compared to General Chemistry labs.

Areas of Agreement / Disagreement

Participants generally agree on the need for thorough preparation before labs, but there are varying opinions on the perceived difficulty and importance of understanding the chemistry involved. No consensus is reached on specific preparation methods or resources.

Contextual Notes

Participants express different levels of confidence regarding their understanding of the lab material and the challenges posed by TA discussions. There is an acknowledgment of the need for accuracy in data collection, but specific strategies for achieving this remain varied.

Who May Find This Useful

Students currently enrolled in Analytical Chemistry courses or those preparing for similar laboratory work may find the shared experiences and strategies beneficial.

I am currently taking an Analytical Chemistry class which has labs in it. I did my first one last week and it wasn't so bad - I still have one more week to finish up my lab write up. This week though we are doing another lab, and my hopes are that I can prepare myself better for this week.

I was just wondering, what you all used to do (those of you who took the course) in order to prepare for the labs? What did you try to focus on during preparation and were there any textbooks that you found that helped with getting a very good grade in the course?

I never really liked analytical chemistry. The labs were a joke compared to Organic. But when you prepare for labs in general, you prepare so you know exactly what you're going to be doing, much like rehearsing before a performance. Focus on which chemicals you need to mix and which samples you need to run on the machine. Worry about the chemistry later when you prepare the report and just make sure you are prepared enough to work efficiently and get good results. That gets you in and out the door as quickly as possible which is important because sometimes there aren't enough instruments for everyone to use at the same time. This means it pays to be the first one to use it so you don't have to wait 3 hours until the first guy is done.
 
Well currently I have been doing just that in terms of knowing what I should do before hand. I have actually so far always finished 20-40 minutes early than the end time.

The only thing that sometimes worries me, is the Discussion I have to have with my TA. In the course during lab time, the TA will take out 4 students together and ask them random questions about the lab. Again I haven't done so bad, but I am waiting for that one question which will stump me. So this is sort of the reason I would like to understand the lab before I do it rather than after while doing my report.

Just be prepared to setup the lab and also to obtain all of the relevant data , it's sometimes nice to have the form of the datasheet already made up prior to the lab , otherwise Analytical Chemistry is pretty close to General Chemistry with the exception of better accuracy and faster times. That's another thing , your data is going to be examined more closely , so make certain that you know what you need to observe.
