Why are metal oxides not categorized as salts?

Salts and oxides can be obtained.

- carbonates are salts. - oxides are...oxides not salts - hydrogencarbonates are salts

Metal oxides are basic oxides.

Metals, Metal-oxides and bases form salts with acids.

Metal oxides are normally bases. Metal oxides are normally bases.

Metal oxides are oxides of metal. They are ionic in nature and form basic oxides. Eg: Na2O, MgO,etc

metal oxides do not react with water .Metal reacts with water and it made metal oxides.

Oxides, Hydroxides, Carbonates, Halides, and Soluble Salts. Oxides, Hydroxides, Carbonates, Halides, and Soluble Salts.

Oxides are compounds of oxygen with another chemical element. Salts are the products of the reactions between acids and bases (neutralization reactions).

A salt refers to any ionic compound excluding oxides. Sodium chloride is a salt because it contains a metal and non-metal (sodium and chlorine), which creates an ionic bond. So generally, you can say that any compound of a metal and non-metal is a salt (without oxides).

characteristics of salts & oxides

No, but their salts are, as are some oxides.

Metal oxides are basic in nature. They are not acidic.

One way is electrolytic reduction of metal cations from molten salts. Another is heating with carbon, which can reduce the metal ions in many metal oxides to elemental metal atoms.

this is because almost all the metal oxides (except aluminum oxide and zinc oxide) are basic oxides .

ammonia, amines, nitrogen oxides, metal nitrates, ammonium salts, diatomic nitrogen molecules, nitrides

Many metal oxides are alkaline and form hydroxides in the presence of water.

Examples: uranium oxides, sodium oxides, lead oxides, aluminium oxide, plutonium oxides etc.

No. A number of metal oxides are basic.

No, metal oxides are basic in nature.

Many ores contain metal oxides. Metal oxides are more stable than metals. Energy is required to break the metal oxygen bond in these metal oxides to release the metal in its elemental form.

Metal oxides are typically basic.

Most metal oxides are Basic oxides, but some like Chromium trioxide, and Molybdenum trioxide are acidic forming Chromate and Molybdate ions respectively.

When acids react with metals, they form salts + hydrogen. If they react with metal oxides/hydroxides, the produce salts + water Examples Acid + Metal --> Salt + Hydrogen H2SO4 + Mg --> MgSO4 + H2 2HCl + 2Na --> 2NaCl + H2 Acid + Metal Oxide --> Salt + Water H2SO4 + MgO --> MgSO4 + H2O 2HCl + Na2O --> 2NaCl + H2O

They become salts or oxides.
