A
It can be used to disinfect drinking water.
B
It is a strong oxidizing agent.
C
It causes cell lysis when free radicals form in water.
D
It is a surfactant.
Verified step by step guidance1
Understand the properties of ozone: Ozone (O₃) is a molecule composed of three oxygen atoms. It is known for its strong oxidizing properties, which make it effective in disinfection processes.
Evaluate the statement about ozone being used to disinfect drinking water: Ozone is indeed used in water treatment facilities to disinfect drinking water due to its ability to kill bacteria and other pathogens.
Consider the statement about ozone being a strong oxidizing agent: Ozone is a powerful oxidizing agent, which means it can accept electrons from other substances, leading to chemical reactions that can destroy microorganisms.
Analyze the statement about ozone causing cell lysis: Ozone can cause cell lysis by generating free radicals in water, which can damage cell membranes and lead to the destruction of cells.
Examine the statement about ozone being a surfactant: A surfactant is a substance that reduces surface tension between two liquids or a liquid and a solid. Ozone does not have surfactant properties; it does not reduce surface tension, making this statement false.
