Mercury (pictured) is the best liquid conductor of electricity.

Why Is Mercury So Good At Conducting Electricity?
Mercury is different to most metals, as it’s actually a liquid at room temperature.

As a metal, mercury is full of charged ions (positive and negative particles), and this makes it a very good conductor of electricity.

Unfortunately, mercury is very expensive, toxic, and difficult to handle. Also, despite conducting electricity pretty well, mercury is a very poor heat conductor.

What Other Liquids Are Good At Conducting Electricity?
Most liquids are good at conducting electricity – especially acidic ones (like the ones that you get in battery acid), or liquids with a lot of ions in them.

Water is an okay conductor of electricity when it’s pure, but it becomes a better conductor when you add salt. This is because salt is full of sodium ions.

What Is The Best Non-Liquid Electricity Conductor?
In general, the best conductors are metals. The most popular conductor of electricity is copper – this is why circuit boards are made using copper sheets.

Pure water will not conduct electricity. For water to conduct electricity, it must contian ions. Pure water (H2O) does not have any ions to conduct electricity.

The strongest acid you can find conducts electricity the best. Just like the acid in a battery.
