Proton transfer and acids
The earlier definitions of acids and bases extend once protons are introduced. An acid is a proton donor: when it dissolves, its molecules ionise and release hydrogen ions, which are simply protons, into the solution. Hydrochloric acid shows this cleanly, splitting into H+ and Cl- ions in water.
What you know already
From Acids, Alkalis & Titrations you know acids as sources of hydrogen ions and alkalis as sources of hydroxide ions. This note deepens both definitions with proton transfer: an acid hands a proton over, and a base takes it in. The same two examples, hydrochloric acid and sodium hydroxide, show each role in action.
Key points of understanding
- An acid is a proton donor.
- Acids ionise in solution, releasing hydrogen ions, which are protons.
- The H+ ions released make the aqueous solution acidic.
- Hydrochloric acid ionises to give H+ and Cl- ions in water.
- A proton and a hydrogen ion are two names for the same particle.
