What oxides does sulfuric acid react with in an aqueous solution? Indicate with which of the following oxides sulfuric acid will react: А1203, С02, ВаО, Na20, CuO. Write down equations of possible reactions.
Sulfuric acid is a strong diacid. Interacts with basic and amphoteric compounds. From the list provided, sulfuric acid will react with all substances, with the exception of acidic carbon dioxide.
A1203, C02, BaO, Na20, CuO
Al2O3 + 3H2SO4 = Al2 (SO4) + 3H2O;
BaO + H2SO4 = BaSO4 + H2O (insoluble barium sulfate is formed);
Na2O + H2SO4 = Na2SO4 + H2O;
CuO + H2SO4 = CuSO4 + H2O (a sign of the reaction is the dissolution of a black precipitate of copper oxide).
