Question

A student set up the arrangement below to prepare and collect dry hydrogen gas:

A. The errors are not specified in the options.
B. Error 1: Missing a gas collection tube. Error 2: Incomplete circuit.
C. Error 1: Incomplete circuit. Error 2: No drying agent.
D. Error 1: Missing a gas collection tube. Error 2: No drying agent.

Answer 1

The correct answer is D. Error 1: Missing a gas collection tube. Error 2: No drying agent.

Step-by-step explanation:

The correct answer is D. Error 1: Missing a gas collection tube. Error 2: No drying agent.

For the setup to prepare and collect dry hydrogen gas, it is essential to have a gas collection tube to capture the hydrogen gas. This is the error mentioned in Option A and Option D. Without a gas collection tube, the hydrogen gas will escape into the environment, making it impossible to collect.

Additionally, a drying agent is necessary to remove any moisture or water vapor from the collected hydrogen gas. This is the error mentioned in Option C and Option D. Water vapor can affect the accuracy of the collected gas volume and can lead to incorrect results.
