Chapter 15: Problem 5

Discuss the properties of the following: (a) Ozone (b) \(\mathrm{SO}_{2}\) (c) \(\mathrm{SeO}_{2}\) (d) \(\mathrm{H}_{2} \mathrm{SO}_{5}\)

Short Answer

Expert verified
Ozone is a triatomic oxygen molecule, beneficial at high altitudes but pollutants at low altitudes. Sulfur Dioxide is a reducing and oxidizing agent, excessive in the atmosphere can lead to acid rain. Selenium Dioxide sublimes at standard pressures, similar to sulfur dioxide in colour and odor, and is a good oxidizing agent. Peroxymonosulfuric Acid is a strong unstable acid, only stable when in a highly dilute form.

Step by step solution

01

Discuss the properties of Ozone

Ozone is a triatomic oxygen (\(O_{3}\)) molecule, with a unique odor. Guessing from the structure, it's unstable, having a half-life of around 30 minutes. It is both a naturally occurring and man-made compound, beneficial at higher altitudes (in the stratosphere) where it forms the ozone layer protecting us from harmful UV rays, but pollutants at low altitudes.
02

Discuss the properties of Sulfur Dioxide

Sulfur Dioxide (\(\mathrm{SO}_{2}\)) is a colorless gas with a pungent smell. It's soluble in water and easily liquefied at room temperature and pressure. It is a strong reducing agent and also has oxidizing properties which contributes to its use in various industrial processes. It is also released into the atmosphere by volcanic activities. Excessive \(\mathrm{SO}_{2}\) in the atmosphere can lead to acid rain.
03

Discuss the properties of Selenium Dioxide

Selenium Dioxide (\(\mathrm{SeO}_{2}\)) is a solid substance that sublimes at standard pressures. It forms a gaseous layer that resembles sulfur dioxide in color and odor. It's a good oxidizing agent, and industrially it's mainly used in the production of selenium salts.
04

Discuss the properties of Peroxymonosulfuric acid

Peroxymonosulfuric Acid (\(\mathrm{H}_{2} \mathrm{SO}_{5}\)), also known as Caro's acid, is a strong but unstable acid. It's colorless and is only stable when in a highly dilute form. It's a strong oxidant and is used in laboratories and other industrial applications.
