What is mercury tailing?

What is mercury tailing?

Mercury reacts with ozone to form an oxide. Meniscus of mercury is lost and mercurous oxide sticks to the glass. It is known as tailing of mercury. On shaking with water, the meniscus is restored.

How is tailing of mercury removed?

Mercury loses it’s lustreness, meniscus and consequently sticks to the walls of glass vessel when it reacts with ozone. This phenomenon is called tailing of mercury. It is removed by shaking it with water which dissolves Hg2O.

Why does ozone form mercury tail?

Answer: being a strong oxidising agent due to presence of nascent oxygen, ozone reacts with mercury and oxidizes it to mercurous oxide. Therefore, mercury loses its meniscus and sticks to glass . This is called tailing of mercury.

Which of the following can be used to test ozone?

Complete Step by step answer: Ozone is tested with the help of mercury i.e $Hg$. The process by which ozone is tested with the help of mercury is known as tailing of mercury.

What is the correct formula for mercury I oxide?

Hg2O
Mercury(I) oxide/Formula

How is ozone prepared from oxygen?

By passing a slow dry steam of oxygen through a silent electrical discharge, oxygen can be converted to ozone. The product formed through this process is known as ozonized oxygen.

What is tailing of mercury give equation?

When ozone is passed through mercury, it loses its meniscus and sticks to the glass due to the formation of mercurous oxide. This is called tailing of mercury. The meniscus can be restored by shaking it with water.

What is tailing of mercury chapter?

How does ozone react with mercury?

This happens because ozone is an oxidizing agent, so when ozone is passed through mercury, ozone oxidizes mercury to mercurous oxide and changes the oxidation state of mercury from zero to one. Ozone is an oxidizing agent. It oxidizes another compound. Gain of oxygen or removal of hydrogen is known as oxidation.

How ozone is tested?

Ozone testing is a method used to determine a rubber or elastomer’s resistance to ozone degradation. The elastomer samples are placed in a special chamber that exposes them to ozone at concentration and duration specified by a testing specification or standard.

What is the chemical formula for mercury I phosphate?

Mercury(I) Phosphate (Hg2)3(PO4)2 Molecular Weight — EndMemo.

What happens to the tailing of Mercury on exposure to air?

The tailing of mercury on exposure to air shows a change in oxidation number by one. (1) True (2) False As ozone passes through mercury it loses the meniscus and sticks to the glass because of mercury oxide formation. This is called mercury tailing. One can recover the meniscus by stirring it with water.

How do you remove the tailing of mercury from glass?

Tailing of mercury is its innate property. It can be removed by adding some impurities in it such as other metal. When ozone is passed through mercury, it loses its meniscus and sticks to the glass due to the formation of mercurous oxide.

What causes mercury to stick to glass?

This basically occurs due to the formation of mercurous oxide (Hg 2 O). Due to this phenomenon, mercury loses its meniscus and starts sticking to the glass. This can be removed by washing with water, as Hg 2 O is soluble in water.

How can the meniscus of mercury be restored?

The meniscus can be restored by shaking it with water. Ozone is oxidizing agent. when ozone is passed through mercury, ozone reacts with mercury and forms mercurous oxide. This basically occurs due to the formation of mercurous oxide. Due to this phenomenon, mercury loses its meniscus and starts sticking to the glass.
