How is ozone prepared ? How does it react with the following ?
Hg

Explanation

Preparation of Ozone :
When a slow dry stream of oxygen is passed through a silent electrical discharge, oxygen is converted to ozone. This product is called ozonised oxygen.
`3O_(2) to 2O_(3), DeltaH^(@)(298K)=142 K//mol`
If high concentration of ozone `(gt 10%)` is required, a battery. of ozonisers can be used. Pure ozone can be condensed in a vessel surrounded by liquid oxygen.
Properties,
`Hg_(2)O` formed sticks to the glass surface and mercury loses its meniscus due to dissolution of `Hg_(2)O` in Hg. This is called tailing of mercury.
