El '''clorur sòdic''', de fórmula NaCl, també conegut com a ''sal de taula'' o ''[[sal comuna]]'' (''halita'', quan és el mineral) és un compost iònic, format per un [[catió]] Na<sup>+</sup> (ió sodi) i un [[anió]] Cl<sup>-</sup> (ió clorur), el NaCl és el producte d'una reacció violenta en la qual un àtom de [[sodi]] ([[metall]] reactiu) reacciona amb un de [[clor]] (un no-metall).
