Acid oxides can enter into reactions: a) decomposition, compound, substitution b) compound, neutralization
Acid oxides can enter into reactions: a) decomposition, compound, substitution b) compound, neutralization, exchange c) compound, exchange, decomposition d) there is no correct answer
The correct answer is b. Oxides that react with bases to form salt and water are called ACID OXIDES. acid oxide always corresponds to a certain acid:
CO2 (carbon monoxide) – H2CO3 (carbonic acid);
SO3 (sulfur oxide VI) – H2SO4 (sulfuric acid);
SiO2 (silicon oxide) – H2SiO3 (silicic acid).
only two metal oxides should be remembered, which are also acidic. These are oxides of chromium and manganese, in which the metals have the LARGEST oxidation state of all possible:
CrO3 (chromium oxide VI) – H2CrO4 (chromic acid);
Mn2O7 (manganese VII oxide) – HMnO4 (manganic acid).
