When a gas is collected over water, the gas is not pure because it is mixed with vapor from the evaporation process of the water.

Partial pressure is the pressure that a gas would have if it took up the entire volume that the mixture of gases currently occupies.

Gas is not pure when it is collected over water because it contains water molecules. Dalton's Law of Partial Pressures can be used to calculate the partial pressure of the collected gas.

Following the determination of the total pressure, the pressure of the water vapor is calculated by consulting a reference table for that particular temperature. By deducting the pressure of the water vapor from the total pressure, one can calculate the partial pressure of the collected gas.
