Question
Carbon dioxide, CO2 reacts with calcium hydroxide, Ca(OH)2, a base to form calcium carbonate (CaCO3), a salt and release water, H2O. The reaction is analogous to an acid-base reaction which produces salt and water. This reaction shows that CO2 is an acidic oxide.
Ca(OH)2 (aq) + CO2 (g) -------> CaCO3 (s) + H2O (l)
Barium oxide, BaO is a basic oxide since it reacts with water to form barium hydroxide, Ba(OH)2 which is known to be a base.
Sulfur trioxide, SO3 is an acidic oxide since SO3 reacts with water to form sulfuric acid, H2SO4 which is a strong mineral acid.
The balanced molecular equations are shown below.
BaO (s) + H2O (l) ------> Ba(OH)2 (aq)
SO3 (g) + H2O (l) -------> H2SO4 (aq)
