Final answer:
The presence of palladium in a Brewer-type anaerobic jar does not cause a specific reaction. Palladium acts as a catalyst to remove oxygen from the jar and create an anaerobic environment, which is ideal for the growth of anaerobic bacteria.
Step-by-step explanation:
In a Brewer-type anaerobic jar, the presence of palladium does not directly cause any specific reaction. The main purpose of palladium in the jar is to catalyze the reaction between hydrogen gas and oxygen gas in the jar, forming water vapor and preventing the buildup of oxygen. This deoxygenation process creates an anaerobic atmosphere, which is favorable for the growth of anaerobic bacteria.
To achieve anaerobic conditions, a chemical reaction takes place inside the jar:
- Palladium catalyst converts hydrogen gas (H2) into water vapor (H2O)
- Water vapor binds with oxygen gas (O2) to form water (H2O)
- Oxygen gas is effectively removed, creating an anaerobic environment
This controlled environment allows anaerobic bacteria to grow and thrive in the absence of oxygen.
