Are oxides liquid?
The Physical States and Structures of Oxides. Matter can exist in one of three physical states at room temperature — solid, liquid or gas.
Are metal oxides soluble?
Soluble metal oxides produce alkalis when dissolved in water. Soluble non-metal oxides produce acids when dissolved in water.

What is the nature of metal oxides?
basic
Thus the nature of metal oxides is basic rather than acidic or neutral. . These compounds are acidic known as carbonic acid and sulphuric acid.
Which type of oxide are formed by metal?
basic oxides
Metals tend to form basic oxides, non-metals tend to form acidic oxides, and amphoteric oxides are formed by elements near the boundary between metals and non-metals (metalloids).
Are metal oxides acidic or basic?
Metallic oxides are basic and non-metallic oxides are acidic.
Are non-metal oxides solid at room temperature?
One non-metal, bromine, is a liquid at room temperature. The other non-metals are solids at room temperature, including carbon and sulfur.
Is iron oxide a solid?
Fe2O3 is an inorganic compound with a chemical name Iron(III) oxide. It is also known as Hematite or Red iron oxide. This compound occurs naturally in rocks of all ages. It appears as a Red-brown solid.
Are oxides solid?
Oxides have a range of different structures, from individual molecules to polymeric and crystalline structures. At standard conditions, oxides may range from solids to gases.
How metal oxides are basic in nature?
Metallic oxides are basic in nature because they react with dilute acids to form salt and water. Group 1 & 2 oxides are highly alkaline in nature that is why group 1 called alkaline metals and group 2 called Alkaline Earth metals.
