Hermann Lux ian 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- n 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-
.

Answer 2

Base = Acid + oxide $(O^-^2)$

Explanation:

Lux-Flood Concept -

• This acid–base theory was proposed by German chemist Hermann Lux in 1939
• It was further enhanced by Håkon Flood circa in 1947
• Hence, known as Lux - Flood Concept

Applications -

According to the Lux-flood concept -

• Bases are defined as any species that loses or give up oxide ion $(O^-^2)$or we can say it is oxide ion donor
• An acid is defined as any species that gains or takes up oxide ions or oxide ion acceptor

Hence,

Base = Acid + oxide $(O^-^2)$

As an example we can see -

$CaO$ → $Ca2^+ + O2^-$

$CaO$ is a base, because we can see in the reaction that calcium oxide loses or gives up $(O^-^2)$   ions.

1. $CaO (base) + SiO_2 (acid)$ ⇄ $CaSiO_3$
2. $MgO (base) + CO_2 (acid)$ ⇄ $MgCO_3$
