Explanation
Rust is iron oxide, which is a basic oxide. Metal oxides are usually basic. They react with acids to form salts and water.
Non-metal oxides are acidic. Amphoteric oxides act as both acid and base. Reducing oxides is not a standard classification.
Remember: Metal oxides are basic. Non-metal oxides are acidic. This is a fundamental pattern.
