Short Answer

Expert verified

Ionic carbides are compounds of carbon with less electronegative elements, reacting with water to produce acetylene. Ionic silicides, formed by silicon and more electropositive elements, have diverse properties like producing silicon hydride gas when reacting with water. Zeolites are microporous aluminosilicate minerals used as commercial adsorbents and catalysts. Chain silicates consist of interlocking chains of silicate tetrahedra, with properties varying by chain configuration. Hydrofluosilicic Acid, used for water fluoridation and ceramics production, is a corrosive compound forming a weakly acidic solution in water.

Step by step solution

Part A: Ionic Carbides

Ionic carbides are a type of carbide that consists of carbon and a less electronegative element. The most common ionic carbide is Calcium Carbide (CaC2). Despite the ionic nature of Ionic Carbides, they react with water to produce acetylene, a property of covalent carbides.

Part B: Ionic Silicides

Ionic silicides are compounds formed by silicon and more electropositive elements. The properties of ionic silicides greatly depend on the size and charge of the cations they contain. For example, Sodium Silicide (NaSi) reacts with water to produce silicon hydride gas (SiH4), demonstrating ionic silicide's diverse properties.

Part C: Zeolites

Zeolites are microporous, aluminosilicate minerals commonly used as commercial adsorbents and catalysts. They are hydrated, and the water molecules can move easily in and out of the voids provided by the zeolites. Due to their large surface area, they are often used in water purification and in the petroleum industry.

Part D: Chain Silicates

Chain silicates, or inosilicates, consist of interlocking chains of silicate tetrahedra, a four-sided shape formed by silicon and oxygen. These chains can be single, double, or triple. The properties of chain silicates depend on the configuration of these chains. Common examples of chain silicates include Pyroxene and Amphibole.

Part E: Hydrofluosilicic Acid

Hydrofluosilicic Acid (H2SiF6) is a compound often used for water fluoridation and in the production of ceramics. It is a corrosive and dangerous acid that forms a weakly acidic solution when mixed with water. It is considered a byproduct of the phosphate fertilizer industry.
