Explanation
According to the Brønsted-Lowry theory of acids and bases, an acid is defined as a substance (molecule or ion) that can donate a proton (a hydrogen ion, H+) to another substance. A substance that accepts a proton is called a base.
- Hydrophilic refers to molecules or surfaces that have an affinity for water ("water-loving").
- Hydrophobic refers to substances that repel or do not mix with water ("water-fearing").
- Protophilic (proton-loving) describes a substance or solvent that has a high affinity for protons and acts as a proton acceptor (a base).
Therefore, a chemical that donates a proton is specifically classified as an acid.
