Quick Answer: When silent electric discharge is passed through oxygen in Siemen Ozoniser The product obtained is?

A slow current of pure and dry oxygen is passed through the annular space. On subjecting oxygen to silent electrical discharge, ozonized oxygen containing 10-15% ozone is formed.

Why silent electric discharge is used in the preparation of ozone from oxygen?

The reaction is initiated by a sparkless or silent electric discharge, to produce less heat, as ozone is prone to decomposing back into oxygen with an increase in temperature (Le Châtelier’s Principle). Hence, ozone is prepared in a specially designed apparatus called an ozonizer to facilitate the above conditions.

What is silent electrical discharge?

The silent electric discharge is a special type of electricity which has no sparks and creates very low amount of heat energy. … That’s why, silent electric discharge is used to prepare ozone in order to maintain the stability of the ozone molecules and to prevent the dissociation into oxygen molecules.

Which of the following is produced when electrical discharges pass through oxygen in the air?

4 Ozone. Ozone (O3), a powerful oxidizing agent, can be produced by passing an electric discharge through a stream of air or oxygen.

How is ozone prepared by passing silent electric discharge?

In this reaction. 3O2⇔2O3 energy is given out.

How is ozone prepared from oxygen?

Ozone is prepared in laboratory by passing silent electric discharge through dry oxygen. By passing the electric current some of the oxygen molecules dissociate and then atomic oxygen combines with oxygen molecules to form ozone.

How ozone is prepared in Siemens Ozoniser?

Siemen’s ozoniser

A slow current of pure and dry oxygen is passed through the annular space. On subjecting oxygen to silent electrical discharge, ozonised oxygen containing 10-15% ozone is formed.

What happens when silent electric discharge is passed on oxygen gas?

When a silent electric discharge is passed through dry oxygen, ozone is formed. Oxygen is never converted into ozone completely and we always obtain a mixture of oxygen and ozone. … Hence, ozone is prepared in a specially designed apparatus called an ozonizer to facilitate the above conditions.

What is meant by silent discharge?

[¦sī·lənt ′dis‚chärj] (electronics) An inaudible electric discharge in air that occurs at high voltage and consumes a relatively large amount of energy.

What is silent electricity?

absence of noise; a state of producing no detectable signs or symptoms. electrical silence in electroencephalography and electromyography, absence of measurable electrical activity in tissue.

What are types of electrical discharge observed in the mesosphere?

Odd electrical discharges akin to lightning, called “sprites” and “ELVES”, occasionally appear in the mesosphere dozens of kilometers (miles) above thunderclouds in the troposphere below. The stratosphere and mesosphere together are sometimes referred to as the middle atmosphere.

When a slow dry stream of oxygen is passed through a silent electrical discharge?

When a slow dry stream of oxygen is passed through a silent electrical discharge, conversion of oxygen to ozone (10%) occurs. The product is known as ozonised oxygen.

Which phenomenon is an example of electric discharge?

Examples of electric discharge phenomena include: Brush discharge. Dielectric barrier discharge. Corona discharge.

Which reagent does not give oxygen as one of the product during oxidation with ozone?

SnCl2​/HCl.
