Final answer:

In this experiment, the hydrogen gas produced will be collected using the water displacement method. The gas displaces water in an inverted bottle, and Dalton's Law is used to account for partial pressures when measuring the gas volume.

Step-by-step explanation:

To collect the hydrogen gas (H₂) produced in this experiment, you will use the water displacement method. This technique involves setting up an apparatus where a reaction flask releases the generated gas into rubber tubing, which then feeds into a water-filled bottle turned upside-down in a pan of water. As hydrogen gas is produced, it enters through the tubing and replaces, or 'displaces,' the water in the bottle. When the bottle is filled with gas, it is sealed, capturing the hydrogen gas inside for measurement.

To precisely measure the volume of hydrogen gas collected and to account for the partial pressures of both the collected gas and water vapor, Dalton's Law is applied. This is crucial for calculating the quantity of hydrogen accurately, something especially important in instances such as titrations where precision is critical.
