Ammoniakbuffers
Ammoniakbuffers (ammonia buffers) are buffer solutions composed of ammonia (NH3) and its conjugate acid ammonium (NH4+). They resist changes in pH when small amounts of acid or base are added, within a limited pH range determined by the NH3/NH4+ system.
Chemistry: The buffering action follows the equilibrium NH3 + H2O ⇌ NH4+ + OH−. The pH can be described
Preparation and components: A buffer is formed from a source of NH3 (aqueous ammonia) and a source
Applications: Ammonia buffers are used in laboratory settings to maintain alkaline conditions for certain enzymatic reactions,
Safety: Ammonia is caustic; handle aqueous ammonia solutions with adequate ventilation. Ammonium salts are less volatile
