Document Summary
According to br nsted and lowry, an acid is a species that loses a proton and a base is a species that gains a proton. Note that positively charged hydrogen ions are called protons. For example, hydrogen chloride is an acid because it loses a proton and water is a base because it gains a proton. In the reverse reaction h3o+ is an acid because it loses a proton and, cl- is a base because it gains a proton. An acid loses a proton and a base gains a proton. Water can accept a proton because it has two lone pairs, either of which can form a covalent bond with the proton. Cl- can accept a proton because any of its lone pairs can from a covalent bond with a proton. Any species that has a hydrogen atom can potentially act as an acid. Any species that has a lone pair can potentially act as a base.
