Water molecules are polar molecules. This means that there is an unequal distribution of charge on the molecule.
In the case of a water molecule, the side of the molecule with the two hydrogen atoms carries a partial positive charge and the side of the molecule with the oxygen atom carries a partial negative charge. This structure enables water molecules to interact with other charged substances and facilitate their dissolution. Therefore, the structure of pure water makes it an efficient solvent.
Water is not a catalyst because a catalyst is a protein that lowers the activation energy of a reaction.
Water is not a solute because solutes are substances that dissolve in a solvent to form a solution.
In order for water to be a good conductor, it must contain dissolved charged particles, which water does not.
