Preparation of Mercury: It can be purified by maens of electrolysis.The electrolytic process needs electrolytic solution dilute nitric acid. In addition, the electrolysis voltage is 2-3V and the current is 3-4A.

Uses of Mercury: It can be used to make tubes, mercury rectifiers and electrodes in the electronics industry. And it also be used in a variety of gauges and thermometers, polarographic analysis dropping mercury electrode, etc.

When you are using Mercury, please be cautious about it as the following:
This chemical can cause burns and has danger of cumulative effects. It is irritating to eyes, respiratory system and skin. And it has danger of serious damage to health by prolonged exposure in contact with skin and if swallowed. In addition, it is toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment. When you are using it, wear suitable protective clothing, gloves and eye/face protection. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. And in case of accident or if you feel unwell, seek medical advice immediately (show label where possible). This material and its container must be disposed of as hazardous waste. You should keep container tightly closed and avoid release to the environment. At last, you can refer to special instructions safety data sheet.

You can still convert the following datas into molecular structure:
(1)SMILES: [Hg+2]
(2)InChI: InChI=1/Hg/q+2
(3)InChIKey: BQPIGGFYSBELGY-UHFFFAOYAU
