Explanations:
Water is compound with chemical symbol H2O. Water is made up of hydrogen and oxygen atom. The presence of the -OH bond in its structure makes it a polar molecule.
It is therefore called universal solvent due to its polar nature and ability to form hydrogen bonds with other molecules. Water is also a universal solvent because substance dissolves easily in it than other chemicals.
The presence of partial positive charges on the hydrogens and a partial negative charge on the oxygen makes it easier to interact with other materials.
