Reactions nonmetal oxides with water

CHLOROCHROMIC ANHYDRIDE (14977-61-8) A powerful oxidizer. Violent reaction with water, producing hydrochloric and chromic acids, and chlorine gas. Potentially violent and explosive reaction with reducing agents, acetone, alcohols, calcium sulfide, combustible materials, gaseous or liquid ammonia, ethers, nonmetal halides, fuels, nonmetal hydrides, fluorine, organic matter, organic solvents, phosphorus, phosphorus trichloride, sodium azide, elemental sulfur, sulfur monochloride, turpentine, urea. Decomposes slowly in light. 

Nonmetal oxides can react with water to form acids. For example, carbon dioxide reacts with water to form carbonic acid CO2 + HjO — HjCOj. What acid forms as the result of the reaction of sulfur trioxide and water Write the equation for the reaction. 

Many nonmetal oxides are acidic in the sense that they react with water to form acids. Looking at the reaction... 

Many nonmetal oxides are Lewis acids that react with water to give Bronsted acids. An example is the reaction of C02 with water ... 

A typical reaction of the nonmetal halides is their reaction with water to give oxoacids, without a change in oxidation number ... 

As we shall see later, borides (as well as oxides, nitrides, carbides, etc.) react with water to produce a hydrogen compound of the nonmetal. Thus, the reaction of magnesium boride with water might be expected to produce BH3, borane, but instead the product is B2ff6, diborane (m.p. -165.5 °C, b.p. -92.5 °C). This interesting covalent hydride has the structure... 

Chemically, nonmetals are usually the opposite of metals. The nonmetallic nature will increase towards the top of any column and toward the right in any row on the periodic table. Most nonmetal oxides are acid anhydrides. When added to water, they will form acids. A few nonmetals oxides, most notably CO and NO, do not react. Nonmetal oxides that do not react are neutral oxides. The reaction of a nonmetal oxide with water is not an oxidation-reduction reaction. The acid that forms will have the nonmetal in the same oxidation state as in the reacting oxide. The main exception to this is N02, which undergoes an oxidation-reduction (disproportionation) reaction to produce HN03 and NO. When a nonmetal can form more than one oxide, the higher the oxidation number of the nonmetal, the stronger the acid it forms. 

The important compounds of nitrogen with hydrogen are ammonia, hydrazine, and hy dr azoic acid, the parent of the shock-sensitive azides. Phosphine forms neutral solutions in water reaction of nonmetal halides with water—hydrolysis—produces oxoacids but no change in oxidation number.
