1. The problem statement, all variables and given/known data Let’s say the % concentrations of CaCO3 (table 5) you obtain from trial #1 and #2 are consistent, while the concentration obtained from trial #3 is significantly higher. Demonstrate, how and where, a wet flask could be involved to explain such a result. Explain in great details. 2.

The attempt at a solution Alright, so we did a lab with calcium carbonate and antacid today, reacting each with HCl and measuring the pressure/temperature before the reaction and then after the reaction. From this we can find the volume, amount, mass, etc. I have no idea as to how to approach this question, it seems as it wouldn't depend on whether the flask is wet or not - because a wet flask with release more CO2 but how does that contribute to the final concentration of calcium carbonate in an antacid tablet? Any hints would be appreciated.
