To show metallic oxides are basic
An oxide is a chemical molecule that contains one or more oxygen atoms and another element, such as lithium dioxide, carbon dioxide, water, etc.
Oxides can be categorised as follows:
Metal-containing binary oxygen compounds are known as metallic oxides, whereas non-metallic binary oxygen compounds are known as non-metallic oxides. Metallic oxides are formed when a metal reacts with oxygen. BaO and MgO are two examples of metallic oxides. Metallic oxides are usually basic in nature. This is because when they react with water, they produce basic compounds.
Non-metallic oxides are formed when a non-metal reacts with oxygen. Non-metallic oxides include, for example, SO2 and CO2. Non-metallic oxides are typically acidic. This is because when they react with water, acidic compounds are formed.
A metal cation and an oxide anion are both present in crystalline solids known as metal oxides. Usually, they interact with water to create bases or acids to create salts. Heating the metal carbonates is a standard method of preparing the alkaline earth oxides.
MCO3 + heat → MO + CO2
Ionic metal oxides, such as those found in alkali and alkaline earth metals, react with water to produce basic metal hydroxide solutions.
M2O + H2O → 2MOH (where M = group 1 metal)
MO + H2O → M(OH)2 (where M = group 2 metal)
They are frequently referred to as basic oxides as a result. They react with acids in normal acid-base reactions to form salts and water by their fundamental behaviour; for example, in the case,
M2O + 2HCl → 2MCl + H2O (where M = group 1 metal).
