Solution
The correct option is A 1
The tailing of mercury is the reaction of mercury with ozone due to which mercury loses its meniscus and it starts sticking to the walls of the thermometer due to the formation of the mercurous oxide. The meniscus can be restored by shaking with water.
The tailing of mercury on exposure to air shows a change in oxidation number by one.
The reaction is as follows:
2Hg+O3→Hg2O+O2
0 +1 per Hg
