| Modern Concept of Acid and Base |
|
| When acids combine with bases, acids give hydrogen ions to the base, and the base accepts them. We have already seen that a hydrogen ion is a proton. So when acid gives away a hydrogen ion, it is in fact giving away a proton. Thus, the base while accepting a hydrogen ion, is accepting a proton. So an acid may be defined as a substance that gives away protons, and a base, as a substance that receives protons. |

| A Base is a proton Acceptor. |
