Direction: Read the passage given below and answer the following questions:

Ozone is an unstable, dark blue diamagnetic gas. It absorbs the UV radiation strongly, thus protecting the people on earth from the harmful UV-radiation from the sun. The use of chlorofluorocarbon (CFC) in aerosol and refrigerator and their subsequent escape into the atmosphere, is blamed for making holes in the ozone layer over the Antarctica. Ozone acts as a strong oxidising agent in acidic and alkaline medium. For this property, ozone is used as a germicide and disinfectant for sterilizing water. It is also used in laboratory for the ozonolysis of organic compounds and in industry for the manufacture of potassium permanganate, artificial silk, etc.

Answer:

Reaction of Ozone with Moist Iodine:

When ozone reacts with moist iodine, it forms hydrogen iodate (HIO3) as the product.

Explanation:

Ozone (O3) is an unstable, dark blue diamagnetic gas that has a strong oxidizing property. It readily reacts with various substances, including iodine (I2).

The reaction between ozone and iodine can be represented as follows:

O3 + I2 + H2O → HIO3 + O2

In this reaction, ozone reacts with iodine and water to produce hydrogen iodate (HIO3) and oxygen gas (O2) as the products.

Explanation of the Reaction:

1. Ozone (O3):
- Ozone is an allotrope of oxygen, consisting of three oxygen atoms bonded together.
- It is highly reactive due to the presence of an unstable oxygen-oxygen bond.

2. Iodine (I2):
- Iodine is a non-metallic element that exists as a diatomic molecule (I2).
- It is a dark purple solid with a characteristic odor.

3. Reaction:
- When ozone reacts with iodine in the presence of water, it oxidizes iodine to form hydrogen iodate.
- The water molecule acts as a catalyst in this reaction.
- The oxygen gas (O2) released during the reaction can be observed as a gas.

4. Hydrogen Iodate (HIO3):
- Hydrogen iodate, also known as iodic acid, is a strong acid.
- It is formed when iodine is oxidized by ozone in the presence of water.
- Hydrogen iodate is a white crystalline solid that is soluble in water.

5. Significance:
- The reaction of ozone with moist iodine is important in the context of the ozone layer.
- The ozone layer in the Earth's atmosphere protects us from harmful UV radiation from the sun.
- However, certain substances like chlorofluorocarbons (CFCs) can deplete the ozone layer.
- The reaction of ozone with these substances, including iodine, helps in understanding the ozone layer's chemistry and potential depletion mechanisms.

In conclusion, when ozone reacts with moist iodine, it forms hydrogen iodate (HIO3) as the product. This reaction has significance in understanding the chemistry of the ozone layer and its depletion mechanisms.
