Nonmetallic oxides are _______ in nature.
Acidic
Nonmetallic oxides are acidic in nature.
Why are they acidic?
When nonmetallic oxides react with water, they dissolve to form acids.
$$\text{Nonmetallic Oxide} + \text{Water} \rightarrow \text{Acid}$$
Key Examples:
Carbon dioxide ($\text{CO}_2$): Reacts with water to form carbonic acid, which is found in carbonated drinks and acid rain.
$$\text{CO}_2 + \text{H}_2\text{O} \rightarrow \text{H}_2\text{CO}_3 \text{ (Carbonic acid)}$$
Sulfur trioxide ($\text{SO}_3$): Reacts with water to form sulfuric acid.
$$\text{SO}_3 + \text{H}_2\text{O} \rightarrow \text{H}_2\text{SO}_4 \text{ (Sulfuric acid)}$$
Because of this acidic property, if you test a solution of a nonmetallic oxide with litmus paper, it will turn blue litmus paper red.
