- Acids and Bases - Definition, Examples, Properties, Uses with Videos & FAQsAn acid is any hydrogen-containing substance that is capable of donating a proton (hydrogen ion) to another substance. A base is a molecule or ion able to accept a hydrogen ion from an acid. Acidic substances are usually identified by their sour taste.
- 13.1.1: Acids and Bases Definitions - Chemistry LibreTextsThe theory developed by Svante Arrhenius in 1883, the Arrhenius definition, states that an acid produces hydrogen ions, H +, in solution and a base produces hydroxide ions, OH −. Later, two more sophisticated and general theories were proposed. These theories are the Brønsted-Lowry and Lewis definitions of acids and bases.
- Acid: Definition and Examples in Chemistry - ThoughtCoAn acid is a chemical species that donates protons or hydrogen ions and/or accepts electrons. Most acids contain a hydrogen atom bonded that can release (dissociate) to yield a cation and an anion in water. The higher the concentration of hydrogen ions produced by an acid, the higher its acidity and the lower the pH of the solution.
- Acid | Definition, Examples, Types, Uses, & Facts | BritannicaAn acid is any substance that in water solution tastes sour, changes blue litmus paper to red, reacts with some metals to liberate hydrogen, reacts with bases to form salts, and promotes chemical reactions (acid catalysis).
- 14.2: Acids: Properties and Examples - Chemistry LibreTextsTwo common indicators are litmus and phenolphthalein. Blue litmus turns red in the presence of an acid, while phenolphthalein turns colorless. Acids react with active metals to yield hydrogen gas. Recall that an activity series is a list of metals in descending order of reactivity.
