I-potassium hydrogen fluoride (i-potassium bifluoride, KHF2 noma HF.KF): usawoti omhlophe owenziwe nge-hydrofluoric acid ne-potassium carbonate; uma ushiswa womile ukhipha i-hydrogen fluoride engenamanzi, futhi okuncane kwawo kwenza i-HF ewuketshezi idlulise ugesi ku-electrolysis. Unobuthi futhi uyagqwala.
