Answer 1

You have made a double post and neither is very good; at least, neither makes sense to me. Perhaps some other tutor can tell what is going on.

Answer 2

Thanks I was thinking the same thing when my professor actually asked this question on our lab report well now I see why no one in lab could figure out the answer. Will print your rtesponse and share. Thank you I knew we were not all confused.

Answer 3

The purpose of leaving the bottles upright in this setup is to collect the oxygen gas produced during the decomposition of hydrogen peroxide.

To understand why the bottles are left upright, let's break down the process step by step:

1. Catalyst Introduction: The catalyst is introduced to accelerate the decomposition of hydrogen peroxide. This reaction produces water and oxygen gas.

2. Condenser: A condenser is used to cool and condense the water vapor produced during the reaction. This helps to separate the water from the oxygen gas.

3. Displaced Water Bottle: This bottle is inverted and filled with water, leaving an air pocket at the top. It is connected to the first upright bottle with tubing. The purpose of this displaced water bottle is to create a suctioning effect. As oxygen gas is produced, it displaces the water in the inverted bottle, causing a drop in pressure and creating a vacuum. This vacuum pulls the oxygen gas from the first bottle through the tubing and into the air pocket of the displaced water bottle.

4. Upright Bottles: The question focuses on the purpose of the remaining upright bottles. These bottles are simply used to collect and store the oxygen gas. Since there is no need for a suctioning effect in these bottles, they are left in an upright position, without any displaced water. The gas collected in these bottles is mostly oxygen, even though it may mix with some air that was already present. The separation of oxygen from the air is not perfect but can be achieved to a significant extent.

To summarize, the upright bottles are left upright in order to collect and store the oxygen gas produced during the decomposition of hydrogen peroxide. The purpose of displaced water bottles is to create a suctioning effect to draw the oxygen gas from the reaction vessel.
