Bookmark or Share- Base Definition in Chemistry - ThoughtCoAnne Marie Helmenstine, Ph.D. Updated on September 29, 2022. In chemistry, a base is a chemical species that donates electrons, accepts protons, or releases hydroxide (OH-) ions in aqueous solution. Bases display certain characteristic properties that can be used to help identify them.

- 6.1: What is an Acid and a Base? - Chemistry LibreTextsArrhenius's Definition of Acids and Bases. The earliest definition of acids and bases is Arrhenius's definition which states that: An acid is a substance that forms hydrogen ions H + when dissolved in water, and; A base is a substance that forms hydroxide ions OH-when dissolved in water.
- Explainer: What are acids and bases? - Science News ExploresThroughout history, chemists have created different definitions of acids and bases. Today, many people use the Brønsted-Lowry version. It describes an acid as a molecule that will give away a proton — a type of subatomic particle, sometimes called a hydrogen ion — from one of its hydrogen atoms.
