Hydrophilic

Water is a polar molecule. No, it doesn’t live with Santa. Being polar means that one side of the molecule is more negative whereas the other side is more positive. In water the oxygen atom has a slightly negative charge and the hydrogen has a slightly positive charge. Hydrophilic substances have an affinity for water, or are water loving. Polar molecules are hydrophilic. They can form hydrogen bonds with water because of their slight charge. Hydrophilic substances are soluble in water. For example, sugar is hydrophilic. As you can observe in the picture above, the sugar that I mixed into the water dissolved completely.
