Lux-Flood definition
an acid as an oxide ion acceptor and a base as an oxide ion donor.(This acid–base theory was a revival of oxygen theory of acids and bases, proposed by German chemist Hermann Lux in 1939, further improved by Håkon Flood circa 1947 ) For example:
- MgO (base) + CO2 (acid) → MgCO3
- CaO (base) + SiO2 (acid) → CaSiO3
- NO3- (base) + S2O72- (acid) → NO2+ + 2SO42-
