Answer 1

Answer:

Acidic oxides, or acid anhydride, are oxides that react with water to form an acid

CO2 in water becomes carbonic acid. Carbonic acid (H2CO3) is a weak acid capable of splitting of a H +. As some of the carbon dioxide dissolves in the water it forms carbonic acid, a weak acid that acidifies the solution.

The oxygen on CaO is binding to H+ ions from the HI. Therefore, it is considered a Bronsted base because it is a proton acceptor. In addition, this reaction is a typical Acid + Base -> salt + water reaction.
