Acidic oxides are compounds formed when nonmetals react with oxygen. They typically have a high affinity for water, allowing them to form acids when dissolved. Common examples include carbon dioxide and sulfur dioxide, which can lead to the formation of carbonic acid and sulfurous acid, respectively. These oxides are often produced during combustion processes and can contribute to environmental issues like acid rain. Acidic oxides can react with bases to form salts, demonstrating their role in acid-base chemistry. Understanding these compounds is essential for studying both industrial processes and environmental impacts.
