Water is the Universal Solvent Keely Greiner Molly Cannon Jiwon Jeong

The Water Molecule The water molecule is polar because of the hydrogen bond, which gives the oxygen atom a slight negative charge and the hydrogen atoms a slight positive charge Hydrogen bonds form between water molecules because the slight positive and negative charges attract water molecules together

Universal Solvent Universal solvent – a substance capable of dissolving all or a large variety of substances (a.k.a. water). Water is defined as the universal solvent because of the polarity of the molecule.

Examples Salt (NaCl) Blood Blood is defined as an aqueous solution, meaning its solvent is water. Water is the primary substance of the blood, and contains all of the blood cells. When sodium chloride is mixed into a glass of water, water molecules surround each individual atom of sodium and chloride, separating the molecules until each atom is isolated by water molecules.
