Reaction with water

Mercury does not react with water.


Reaction with oxygen

On strong heating, mercury forms into a red powder of mercury(II) oxide.

mercury + oxygen > mercury(II) oxide
2Hg(l) + O2(g) > 2HgO(s)


This reaction only occurs around 350C. However, above 400C, mercury(II) oxide decomposes back into the elements. In fact, this is an important experiment carried out by J. Priestley in 1774, leading to the discovery of oxygen.


Reaction with dilute acids

Mercury does not react with dilute hydrochloric and sulfuric acids. However, it can react with concentrated sulfuric and nitric acids.

Mercuy only reacts very slowly with dilute nitric acid, to produce mercury(I) nitrate, Hg2(NO3)2.
