Some metal oxides are amphoteric in nature
WebJul 1, 2024 · The question assumes that if silicon were a metal, it's $\ce{MO2}$ oxide would be basic. But in general $\ce{MO2}$ oxides of most metals are not purely basic but amphoteric. Titanium, for instance, is known to form titanates and its dioxide reacts with sodium hydroxide solutions even at ambient temperature .Purely basic metal oxides … WebAluminium hydroxide is amphoteric. Like sodium or magnesium hydroxides, it will react with acids. This is showing the basic side of its nature. With dilute hydrochloric acid, a colourless solution of aluminium chloride is formed. Al(OH) 3 + 3HCl AlCl 3 + 3H 2 O. But aluminium hydroxide also has an acidic side to its nature.

WebA chemical compound with the anion O 2- is an oxide. Some people use the term to refer to any chemical in which the anion is oxygen. There are many types of oxides, but the most common are metal oxides (such as Ag 2 O and Fe 2 O 3). Metals react with oxygen in the air or water to form oxides, and metal oxides can become gaseous oxides at high ... Weboxide, any of a large and important class of chemical compounds in which oxygen is combined with another element. With the exception of the lighter inert gases (helium [He], neon [Ne], argon [Ar], and krypton [Kr]), oxygen (O) forms at least one binary oxide with each of the elements. Both metals and nonmetals can attain their highest oxidation states (i.e., …
