What is tailing of mercury How is it remove?
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 forms 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.
What is the compound for Hg2O?
Hg2O
Mercury(I) oxide/Formula
What is the definition of tailing?
Definition of tailing 1 : residue separated in the preparation of various products (such as grain or ores) âusually used in plural. 2 : the part of a projecting stone or brick inserted in a wall.
Is tailing of mercury test for ozone?
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.
What does mercury poisoning II tailing of mercury mean?
This is called tailing of mercury. It is known to you that tailing of mercury is when the mercury (Hg) sticks to the sides of a test tube. When ozone is passed through mercury, it loses its meniscus and sticks to the glass due to the formation of mercurous oxide. This phenomenon is called tailing of mercury.
What is meant by ozone hole?
The term ‘ozone hole’ refers to the depletion of the protective ozone layer in the upper atmosphere (stratosphere) over Earth’s polar regions. Polar stratospheric clouds create the conditions for drastic ozone destruction, providing a surface for chlorine to change into ozone-destroying form.

What is peak tailing?
Peak tailing is the most common chromatographic peak shape distortion. Compounds possessing amine and other basic functional groups interact strongly with such ionised silanol groups, producing tailing peaks.
What are tailings used for?
Tailings ponds are used to store the waste made from separating minerals from rocks, or the slurry produced from tar sands mining. Tailings are sometimes mixed with other materials such as bentonite to form a thicker slurry that slows the release of impacted water to the environment.
What is tailing of mercury with example?
It is known to you that tailing of mercury is when the mercury (Hg) sticks to the sides of a test tube. When ozone is passed through mercury, it loses its meniscus and sticks to the glass due to the formation of mercurous oxide. This phenomenon is called tailing of mercury.
