Acid oxide commodity: acidic oxide
Pinyin: suanxingyanghuawu
English name: acid (IC) oxide
Description: acid oxide is a kind of can with water transamination acid or alkali transamination with salt and water oxide. General is a non-metallic element of transition metal oxides and certain elements of high prices oxide. For example sulphur trioxide SO3, five oxidation 2 phosphorus P2O5 and seven oxidation 2 manganese Mn2O7, three chrome oxide CrO3 etc.
We know with acid, alkali salt and water and reacts with certain alkali nonmetallic oxide reaction, also generate salt and water. For example
2NaOH + H2SO4 = Na2SO4 + 2H2O
2NaOH + CO2 = Na2CO3 + H2O
Ca (OH) 2 + SO3 = CaSO4 + H2O
The above reaction showed that carbon dioxide, sulphur trioxide with acid properties similar. Therefore, people put carbon dioxide, sulphur trioxide such reacts with alkali salt and water oxide, called acid oxide.
Non-metal oxide most is acidic oxides, our familiar nonmetal oxide, carbon monoxide and nitric acid oxide, usually not be included under no acid oxide.
Properties and other:
1, acid oxide most can directly combined with water generated oxygen-bearing acid.
The CO2 + H2O = H2CO3
Low SO3 + H2O = H2SO4
SO2 + H2O = H2SO3 (sulfite)
2, oxygen acid can also thermal decomposition an acidic oxides. For example, will be available sulfuric acid heating three oxygen
Of sulfur and water:
H2SO4 = SO3 ↑ + H2O
Here sulphur trioxide is seen as the products of sulfuric acid after dehydration, so also the acid oxide called anhydride.
SiO2, N2O5, also be acid oxide, but silica insoluble in water, can't directly generate silicate combined with water
3, to judge the acid oxide is the most important basis for chemical reaction after the element combining remain unchanged.
Exception:
Silica is a more specific acid oxide.
Silica can and hydrofluoric acid reaction, but not with water reaction.
Note:
Acid oxide mostly nonmetal oxide
Most of the non-metallic oxide is acid oxide
Oxygen acid only acid oxide
