Potassa

Potassa, vel sal alkalinus,^[1] est nomen commune kalii carbonatis (K₂CO₃) et aliorum salum quibus ionta kalii (K⁺) insunt.^[2]

Nomen derivatum est a nomine Batavo potasch (hodie: potas), i.e. 'ollae cinis',^[3]^[4] quia parari solebat ligni cinere in aqua solvendo, deinde colando, postremo solutione in olla ad siccitatem coquenda. Aevo Medio potassa 'alkali' appellabatur, a nomine Arabico القلي al-qili, a verbo قلی qalā, i.e. 'coquere'.^[5]^[6] Ex his duobus nominibus nomina invicem elementi kalii vel potassii derivata sunt.
