xides are very reactive and will react with water and carbon dioxide to form hydroxides and bicarbonates and carbonates. Sulfides are soluble, will hydrolize to form H2S, also will react with heavy metals to precipitate their sulfides, also can react with atmosferic SO2 and nitrogen oxides and evolve H2S. Now, sodium carbonate is actually present in nature! In general sodium and potassium carbonates can easily react with sulfur and nitrogen oxides and evolve CO2. Also reaction with calcium, magnesium and heavy metal ion salts would precipitate carbonates and hydroxides of those metals while forming different salts of sodium and potassium. Hope it helps
