It concentrates on the structural differences between carbon dioxide and silicon dioxide, and on the trends in acid-base behavior of the oxides down The structures of carbon dioxide and silicon dioxide The physical properties of carbon dioxide differ significantly from those of silicon dioxide (also known as silicon(IV) oxide or silica). Carbon dioxide is a gas whereas silicon dioxide is a hard, high-melting solid. The other dioxides in Group 4 are also solids, making the structure of carbon dioxide the anomaly. The structure of carbon dioxide The fact that carbon dioxide is a gas indicates that it consists of small, simple molecules. Carbon can form these molecules beca...

Classification Of Oxides This topic educates with the classification of oxides based on the nature and properties of compounds. Oxides are binary compounds formed by the reaction of oxygen with other elements. What are Oxides? The classification of oxides is done into neutral, amphoteric and basic or acidic based on their acid-base characteristics. • An acidic oxide is an oxide that when combined with water gives off an acid. • A basic oxide is an oxide that when combined with water gives off a base. • When a substance reacts chemically, both as a base or acid is termed as amphoteric oxide. • Neutral Oxide is one that neither has an acidic characteristic nor a basic one. Metal Oxides have an oxidation number of -2 and generally comprise an oxygen anion. The Earth’s crust is mostly made up of oxides that are solid. Oxide coatings can get formed over pure elements too, for instance, a foil made of aluminium gets covered by a thin skin of Al 2O 3, and this skin defends the rest of the foil from Also read: • Classification Of Oxides Depending upon nature and the properties exhibited by compounds, they are classified into • Acidic oxides • Basic oxides • Amphoteric oxides • Neutral oxides Basic oxide: Metals react with oxygen to give basic compounds of oxygen. These compounds are usually ionic in nature. Group 1, 2 and lanthanides form basic compounds of oxygen when they react with dioxygen. During the formation of these compounds, a large amount of energy is released. These co...

Amphoteric oxides are the those oxides which behave both as acidic oxides as well as basic oxides. e.g aluminium oxide and zinc oxide. An amphoteric oxide is one that can act as either an acid or a base. Generally non-metallic oxides are acidic and metallic oxides are basic. Some non-metallic oxides are neutral and some metallic or semi metallic oxides are amphoteric. There are a number of exceptions to these generalizations. What are amphoteric oxides? [ | ] Amphoteric oxides are the oxides that behave as both acidic and basic oxides. Amphoteric Oxides have features of acidic as well as basic oxides that neutralize both acids and bases.” Amphoteric oxides dissolve in water to form alkaline solutions. Alkaline solutions contain hydroxide ions. Thus aluminium oxide (Al2O3) reacts with hydrochloric acid to form aluminium chloride and water. With sodium hydroxide solution it forms sodium aluminate (NaAlO2) and water. Other common examples of amphoteric oxides include ZnO, SnO and PbO. How to identify amphoteric oxides [ | ] Oxides are compounds of metals or nonmetals with oxygen. There are four types of oxide. Amphoteric oxides are classified as metal oxides that react with both acids as well as bases to create salts and water. Amphoteric oxides, among many others, include lead oxide and zinc oxide. Examples include amino acids and proteins that have classes of amine and carboxylic acids and molecules that can be self-ionized, such as water. Amphoteric oxides are oxygen compo...
