alkali词源

alkali

alkali: [14] English acquired alkali via Latin from Arabic al-qalīy ‘the ashes’, a derivative of the verb qalay ‘fry’. The implicit reference is to the plant saltwort (Latin name Salsola kali), which was burnt to obtain its alkaline ashes (Chaucer’s canon’s yeoman, the alchemist’s assistant, mentions it: ‘Salt tartre, alcaly, and salt preparat, And combust matieres, and coagulat’, 1386). The modern chemical sense of a compound which combines with an acid to form a salt was first used in 1813, by the chemist Sir Humphry Davy.

alkali (n.)

late 14c., \"soda ash,\" from Medieval Latin alkali, from Arabic al-qaliy \"the ashes, burnt ashes\" (of saltwort, a plant growing in alkaline soils), from qala \"to roast in a pan.\" The modern chemistry sense is from 1813.
