Is germanium oxide acidic or basic?
So, silicon forms acidic oxide and lead form basic oxide. Germanium and tin both lie in between the groups, so they form amphoteric oxide.
What type of solid is GeO2?
Germanium dioxide, also called germanium oxide, germania, and salt of germanium, is an inorganic compound with the chemical formula GeO2. It is the main commercial source of germanium. It also forms as a passivation layer on pure germanium in contact with atmospheric oxygen.
Is germanium dioxide amphoteric?
GeO is not well characterised. It is amphoteric dissolving in acids to form germanium(II) salts and in alkali to form “trihydroxogermanates” or “germanites” containing the Ge(OH)3− ion….Germanium monoxide.

Is germanium oxide ionic or covalent?
All the carbon group atoms, having four valence electrons, form covalent bonds with nonmetal atoms; carbon and silicon cannot lose or gain electrons to form free ions, whereas germanium, tin, and lead do form metallic ions but only with two positive charges.
Is SiO2 an amphoteric oxide?
So SnO2 is an amphoteric oxide. CaO is basic in nature, while SiO2 and CO2 are acidic in nature. Amphoteric oxides can be defined as oxides that can behave as an acid and a base to produce salt and water.
Is germanium oxide a solid?
Germanium dioxide, also called germanium oxide, germania, and salt of germanium, is an inorganic compound with the chemical formula GeO2. It is the main commercial source of germanium….Germanium dioxide.

What is the molecular geometry of GeO2?
Answer: GeO2 has a linear geometry and H2O has a bent geometry.
What type of oxide is germanium oxide?
Which is an amphoteric oxide CO2 co geo2 SiO2?
The correct option is: a SnO2 Explanation:SnO2 reacts with acid as well as base. So SnO2 is an amphoteric. CaO is basic in nature while SiO2 and CO2 are acidic in nature.
Which type of oxide is germanium oxide?
Germanium dioxide, also called germanium oxide, germania, and salt of germanium, is an inorganic compound with the chemical formula GeO2. It is the main commercial source of germanium….Germanium dioxide.

Does germanium oxide dissolve in water?
Germanium oxide is insoluble in water and hydrochloric acid; it dissolves in alkaline solution to generate germanate. Germanium oxide materials include two kinds of germanium monoxide GeO and germanium dioxide GeO2. Germanium monoxide is a black needle-like crystal, which sublimates at 710°C and is insoluble in water.
What compounds does germanium form?
The two most important compounds of germanium are the dioxide (GeO 2) and the tetrachloride (GeCl 4). Germanates , formed by heating the dioxide with basic oxides, include zinc germanate ( Zn 2GeO 4), used as a phosphor (a substance that emits light when energized by radiation).
Is germanium an amphoteric metal?
Germanium is amphoteric, so it is soluble in molten alkali, peroxide alkali, alkali metal nitrate or carbonate. Germanium is stable at room temperature, but it can also form GeO monolayer, which will gradually become GeO 2 monolayer over time.
