Pure water can conduct electricity, but it is very weak (conductivity can be ignored in daily life) and belongs to extremely weak electrolyte. Due to the dissolution of other electrolytes, there are more positive and negative ions in water in daily life, and its conductivity is enhanced.

Extended data:

The density of water is the highest, which is 3.982℃ and 1000 kg/m 3. When the temperature is higher than 3.982℃ (which can also be ignored as 4℃), the density of water decreases with the increase of temperature; when the temperature is 0 ~ 3.984℃, water contracts and expands, and the density increases with the increase of temperature.

Seen from space, the earth we live in is very round, because the equatorial radius of the earth is only 0.33% longer than the polar radius. The earth is a very beautiful blue sphere. Water is the most abundant natural substance on the earth surface, covering more than 7 1% of the earth surface. The earth is a veritable water polo.

If the temperature continues to rise above 3.982℃, the law of general substances expanding with heat and contracting with cold will prevail. When the water temperature drops to 0℃, water becomes ice. When water freezes, almost all molecules associate together to form a huge associated molecule.

The arrangement of water molecules in ice is that each oxygen atom has four hydrogen atoms as its neighbors and two hydrogen bonds. This arrangement leads to an open structure, and there are large gaps in the structure of ice, so the density of ice is inversely proportional to the density of water at the same temperature.
