Chapter 22: Problem 4

You have two glass bottles, one containing oxygen and one filled with ozone. How could you determine which one is which? [Section 22.5\(]\)

Short Answer

Expert verified
To determine which bottle contains oxygen (O2) and which contains ozone (O3), first observe the color of the gas in the bottles. Oxygen is colorless and ozone is pale blue. If the color difference is not enough, perform a smell test; ozone has a distinct smell similar to chlorine or bleach, while oxygen is odorless. Optionally, perform a chemical test using moistened potassium iodide (KI) paper – ozone will cause a yellowish-brown color change while oxygen will not.

Step by step solution

01

Observe the color of the gas in the bottles

Look closely at the two bottles and compare the colors of the gases. Oxygen is a colorless gas, while ozone has a pale blue color. The bottle containing the pale blue gas is the ozone.
02

Perform the smell test

If the color difference is not enough to determine which bottle contains oxygen and which contains ozone, you can attempt a smell test. Open both bottles and carefully smell the gas released. Ozone has a distinct smell, often described as similar to chlorine or bleach. Oxygen, on the other hand, is odorless. The bottle with the distinct smell contains ozone.
03

Perform a chemical test (optional)

If the smell test is inconclusive or you want further confirmation of the identity of the gases, you can perform a chemical test. Expose a piece of moistened, clean, and uncolored paper with potassium iodide (KI) to each bottle's gas. Ozone will oxidize the iodide (I-) to iodine (I2), which reacts with the water to form a yellowish-brown color on the paper. No color change will occur with oxygen. The bottle that caused the color change on the paper contains ozone. By following these steps, you can determine which bottle contains oxygen and which contains ozone based on their distinct properties.
