How do you prepare KO₃? Mention the magnetic behaviour of O₃⁻.

Potassium superoxide (KO₃) can be prepared through a reaction between potassium hydroxide (KOH) and oxygen (O₂) under specific conditions. Here’s a simple overview of the process:

Preparation Steps

• Reactants: Start with potassium hydroxide and an oxygen source.
• Reaction: Heat the potassium hydroxide in the presence of oxygen. This can be done in a controlled environment to ensure proper reaction conditions.
• Formation: The reaction will yield potassium superoxide, which can be collected and purified.

Magnetic Behavior of O₃⁻

The ozone anion (O₃⁻) exhibits interesting magnetic properties. It is known to be paramagnetic, meaning it has unpaired electrons that allow it to be attracted to magnetic fields. This behavior is due to the presence of these unpaired electrons in its molecular structure, which contributes to its overall reactivity and stability.

In summary, KO₃ is synthesized through a reaction involving potassium hydroxide and oxygen, while the O₃⁻ ion displays paramagnetic characteristics due to its unpaired electrons.
