Question

what is lux flood model

Answer 1

Lux-Flood Definition (1939):

According to this theory, acid and base is define as, acid is an oxide acceptor and base is an oxide donor.

Example:

Here, CaO donates oxygen, therefore, it is a basic oxide. SiO 2 is an oxide acceptor, hence, it is a acidic oxide.

Merits and demerits:

Merit:

This approach emphasizes the acid and basic-anhydride aspects. Acidic oxides are acid anhydride and in the aqueous medium generate protonic acids, while, basic oxides are basic anhydride and generate hydroxyl ion in the aqueous medium.

Demerit:

The usefulness of this concept is limited to inorganic metal oxide and their reactions in molten state.

Answer 2

Lux floor. According to this theory acid and base is defined as, acid is an oxide acceptor and base is an oxide donor. Example sio 2is a oxide acceptor hence it is a acid oxide
