These are ionic bonds, covalent bonds, and hydrogen bonds. Hydrophilic means that the molecule attracts water molecules and is soluble in water. This hydrophobicity is beneficial for the oxygen reduction reaction at the electrode interface as it prevents poisoning species from being adsorbed onto the surface of the electrode. How bond strengths affect physical properties of substances The physical properties of biological substances depend on the intermolecular forces present. A hydrophilic molecule is one that has an affinity for water and other polar solvents. Therefore, understanding the chemical structure of an ion can help determine whether it is hydrophobic or hydrophilic.
