What is Ozone?

  • Ozone, , an unstable, blue, diamagnetic gas with a characteristic pungent odor, protects the earth and its inhabitants from intense ultraviolet radiation from the sun.
  • Ozone is an allotropic molecular form of oxygen containing three atoms of oxygen () . Ozone is generated through the passage of oxygen through a high voltage potential resulting in the attachment and formation of a third oxygen atom. The molecular formula for ozone () was established by Soret (1863) by taking the ratio of the change in volumes when mixtures were either heated or exposed to turpentine and cinnamon oil. The word ‘ozone’ comes from the Greek word ‘ozein’ which means ‘to smell’ . This meaning comes from ozone at the ground level, which gives off a pungent, acrid odour.

Chemical Properties of Ozone –

Ozone dissolves in water resulting in the formation of hydrogen peroxide. The chemical equation is given below.

Ozone reacts with lead sulfide resulting in the formation of lead sulfate. The chemical equation is given below.

Uses of Ozone –

  • Ozone used at water treatment plants without filtration systems.
  • Ozone may also be formed by commonly used equipment such as photocopiers, laser printers, and other electrical devices.
  • In medicine, by limiting the effects of bacteria, viruses, fungi, yeast, and protozoa, ozone therapy is used to disinfect and treat diseases.
  • Several ozone-depleting compounds possess properties that make them good refrigerants that is, they can efficiently transfer heat from one location to another.

Ozone Formula

  • Ozone formula, also known as Trioxygen formula or Triatomic Oxygen formula is explained in this article. This inorganic molecule is an allotrope of oxygen. It consists of three atoms of oxygen, with one single bond, one double bond and an additional of two partial charges viz a negative charge and a positive charge. The “V” angle between the central carbon and the other two carbons is . The chemical or molecular formula of Ozone is .
  • Trioxygen is a pale blue to colourless gas and has a pungent, sharp smell. It has no smell but has a bitter, hard, saline taste. It is insoluble in water but it is soluble in sulfuric acid and carbon tetrachloride. Ozone is generated from dioxygen due to the action of electrical discharges and ultraviolet light within the atmosphere of the earth.

Safety Measures

  • This inorganic gas compound can cause eyes and skin irritation.
  • It can cause genetic defects if inhaled or ingested.
  • It is a strong oxidant and is highly toxic to the aquatic habitat.

Question

What Exactly is Ozone?

Answer: Ozone () is an highly reactive gas that consists of three oxygen atoms. It is both a natural product and a man-made product, found in the upper atmosphere of the Earth. (Stratosphere) , and lower (troposphere) atmosphere. Ozone impacts life on Earth in either good or bad ways, depending upon where it is in the atmosphere.

Is Ozone Toxic to Breathe?

Answer: Ozone can be detrimental to safety, be it in its pure form or combined with other chemicals. Ozone can cause damage to the lungs when inhaled. Relatively low ozone levels can cause pain in the throat, coughing, shortness of breath and inflammation in the lungs.

Is Ozone a Resonance Structure?

Answer: Ozone, or , has two major resonance structures which contribute equally to the molecule՚s overall hybrid structure. The two arrangements are similar to the standpoint of equilibrium, each having a positive and negative formal charge on two of the oxygen atoms.

How Many Lone Pairs Are in Ozone?

Answer: One single pair. To bring it all together, Ozone has 18 valence electrons out of which is one single pair of electrons.

Why is Ozone Bent Instead of Linear?

Answer: Describe why ozone does have a bent shape rather than a linear shape. The nonbonding electron domain takes up space and makes the molecule bent. Ozone has fewer lone pairs than water, thus a larger angle between bonds.

Explain the Process to Estimate Quantitatively

Answer:

Ozone is estimated with the help of potassium iodide, whenozoneand potassium iodide react, iodine is liberated. The iodine obtained is the treated against a standard solution of sodium thiosulphate using starch as an indicator
