Analysis of an Antacid Using the Ideal Gas Law - Experiment
Why must you equalize the pressures before taking any volume measurements in this experiment?
Homework Answers
When the water level inside and outside the gas collection tube are equal, the pressure of the air and the collected gas are equal. Therefore, the measured air pressure can be used for the pressure of the mixture of gases in the collection tube after equalizing the water levels you can go through the volume measurement .that's why it is important to equalize the pressure before taking volume measurement.

The ideal gas law describes the relationship among the volume of an ideal gas (V), its pressure (P), its absolute temperature (T), and number of moles (n): PV=nRT Under standard conditions, the ideal gas law does a good job of approximating these properties for any gas. However, the ideal gas law does not account for all the properties of real gases such as intermolecular attraction and molecular volume, which become more pronounced at low temperatures and high pressures. The van...
