Final answer:
Compounds of representative metals with oxygen can be obtained experimentally through different methods, including heating corresponding hydroxides, nitrates, or carbonates. The resulting compounds can be categorized into oxides, peroxides/superoxides, and hydroxides.
Step-by-step explanation:
Compounds of the representative metals with oxygen exist in three categories: (1) oxides, (2) peroxides and superoxides, and (3) hydroxides. Compounds of representative metals with oxygen can be obtained experimentally through different methods, including heating corresponding hydroxides, nitrates, or carbonates. The resulting compounds can be categorized into oxides, peroxides/superoxides, and hydroxides.
The most common method for producing oxides is by heating the corresponding hydroxides, nitrates, or carbonates. Heating the metal or metal oxide in oxygen may lead to the formation of peroxides and superoxides. The soluble oxides dissolve in water to form solutions of hydroxides. Most metal oxides are base anhydrides and react with acids. The hydroxides of the representative metals react with acids in acid-base reactions to form salts and water.
