Does the reaction of a main-group nonmetal oxide in water produce an acidic or a basic solution? Write a balanced equation for the reaction of a Group 6A(16) nonmetal oxide with water.

Answer :

Answer:

They form acidic solutions

SO2(g) + H2O(l) --> H2SO3(aq)

SO3(g) + H2O(l) --> H2SO4(aq)

Explanation:

Group 6 elements are elements on the periodic table with 6 atoms on their valence shell. Metallic properties increases down the group from oxygen through polonium. Examples are oxygen, polonium, sulphur etc.

Group 6 nonmetal oxides react with water to form acidic solutions, this is because the oxides of nonmetallic elements are basic in nature.

Sulphur exhibits a wide range of oxidation states ranging from +2 to +6. So its oxides are SO2 and SO3.

Example:

SO2(g) + H2O(l) --> H2SO3(aq)

SO3(g) + H2O(l) --> H2SO4(aq)
