Which of the following statements about the reaction of a non-metallic oxide with a base is/are correct? Statement I: The reaction of non-metallic oxide with base produces salt and water. Statement II: Non-metallic oxides are acidic in nature.

Non-metallic oxides are generally acidic in nature because they react with water to form acidic solutions. Because they are acidic, they react with bases to produce salt and water, a process similar to the neutralization reaction between an acid and a base. In contrast, most metallic oxides are basic in nature and react with acids to form salt and water. Non-metallic oxides of sulfur and nitrogen released from factories react with rainwater to form acid rain, which has a pH lower than 5.6.
