Term | Definition |
---|---|
acid | Any substance that donates hydrogen ions according to the Bronsted-Lowry model. |
aqueous solution | A water-based solution. |
base | Any substance that accepts hydrogen ions according to the Bronsted-Lowry model. |
buffer | A weak acid or base in solution that resists changes in pH when a moderate amount of either an acid or base is added. |
hydronium ion | The cation formed by the self-ionization of water (H3O). |
hydroxide ion | The anion formed by the self-ionization of water; OH |
indicator | A substance that changes color in the presence of an acid or base. |
neutralization | The reaction between an acid and a base that in an aqueous solution produces a salt and water. |
pH | A unitless number between 0 and 14 that tells how acidic or basic a substance is. |
salt | A substance that is formed from the combination of a base cation and an acid anion in a neutralization reaction. |
strong acid | An acid in which all or most of the molecules produce hydrogen ions in an aqueous solution. |
strong base | A base that readily produces large numbers of hydroxide ions in an aqueous solution. |
weak acid | An acid that produces few hydrogen ions in an aqueous solution. |
weak base | A base that produces few hydroxide ions in an aqueous solution. |
