Question

Two acidic oxides which forms carbonic acid and sulphuric acid
​

Answer 1

Answer:

Acidic oxides, or acid anhydride, are oxides that react with water to form an acid, or with a base to form a salt. They are oxides of either nonmetals or of metals in high oxidation states. ... For example, sulfurous acid (SO2), sulfuric acid (SO3), and carbonic acid (CO2) are acidic oxides

Explanation:

Answer 2

Answer:

The oxidation states of non metals nitrogen, phosphorus, sulphur and chlorine are N2O5, P4O10, SO3 and Cl2O7 are +5, +5, +6 and +7 respectively. Thus, chlorine has the highest oxidation state. Hence, Cl2O7 is the most acidic oxide.
