is this possible? CaO + SiO2 --> CaSiO3. why?

Question

can u also answer this,

can a basic oxide react with an acidic oxide?

if yes, what are the products? and is there any exceptions?

if no, why?

thx alot :)

Answer 1

Yes, this is possible.
In extraction of ores when concentration of ore is carried out then a part of gangue (worthless material) and the ore still contain some impurities. Then such substances combine with the gangue to form light easily fusible material, called flux and the fusible material is called slag.
When the ore is associated with basic impurities like FeO, the flux used is some acidic substance such as silics, borax. The chemical reaction involved in the formation of slag from a basic gangue is,
CaO + SiO2 = CaSiO3
(Gangue) (Flux) (Slag)
If the ore is associated with acidic impurities like SiO2, some basic fluxes like CaCO3, MgCO3, are used to remove the gangue. For example:
SiO2 + CaCO3 = CaSiO3
(Gangue) (Flux) (Slag)
If you still want to something extra, then search on METALLURGY.

Answer 2

This reaction is certainly possible and it is the basis of silica (SiO2) removal in the BOS (Basic Oxygen Steelmaking) process. A similar process occurs in the Blast Furnace but it is driven from calcium carbonate - CaCO3.

Reaction of an acidic and basic oxide is possible. The reaction products are the salts of the corresponding acid with the metal ion of the base. Mostly these reaction would occur by reacting the oxide with water first.

Another example of your example along your line would be sulphur dioxide passed over sodium oxide would make a sodium sulphite solid.

Answer 3

Sio2 Cao

Answer 4

The reaction of metal oxides (basic anhydrides) with nonmetal oxides (acid anhydrides) to form salts (and no change in oxidation state for the metal and nonmetal) is a common reaction.

Answer 5

i think it can react, because silicon is amphoteric right?
