Titration
Errors during the experiment
3. There is an air bubble in the tip of the buret which is not removed prior to the titration experiment.
The bubble leaves during the course of titrant addition,
The final titration volume would be,
d) too great, this titration is ruined
We would read larger volume of titrant in this case as the space occupied by bubble actually had no titrant in it.

explain the effect of each of thes following sources of error on the molarity of acetic acid as determined in this experiment stating whether the concentration of acetic acid obtained would be too high or too low. a. The buret is contaminated with an acid solution b. The buret contains a larger air bubble in the tip, which disappears in the course of a titration. c. A small volume of the acid solution is spilled when you transfer it into...

In this lab, you will be breathing into a 5 L mixing chamber. The mixing chamber will start with “regular” air (20.93 vol% O2, 0.04 vol% CO2, and 79.03 vol% N2). You will inhale air through your nose (which is exposed to “regular” air) and exhale through your mouth into the mixing chamber. As your exhaled air is added into the chamber, an equal volume of air leaves the other end of the chamber so that the system remains at...
