Metal oxides form alkalis when they dissolve in water. Non-metal oxides for acids. For example: carbon dioxide + water --> carbonic acid magnesium oxide + water --> magnesium hydroxide
Metal oxides can be basic, acidic, or amphoteric depending on the metal and the oxidation state of the metal ion. Basic metal oxides react with acid to form a salt and water, while acidic metal oxides react with base to form a salt and water. Amphoteric metal oxides can act as both an acid and a base depending on the reaction conditions.
in some rare cases it can transform into water (h20)
Acidic oxides are compounds that react with water to form acidic solutions. These oxides typically contain nonmetals, such as sulfur or nitrogen, and when they dissolve in water, they produce acidic solutions capable of neutralizing bases. Examples of acidic oxides include sulfur dioxide (SO2) and nitrogen dioxide (NO2).
Combining a non-metal oxide with water will typically form an acidic solution. Non-metal oxides, such as sulfur dioxide or carbon dioxide, react with water to produce acids like sulfuric acid or carbonic acid.
Not all oxides dissolve in water. Some oxides, such as alkali metal oxides and alkaline earth metal oxides, are soluble in water and form basic solutions. However, other oxides, like non-metal oxides, are typically insoluble or react with water to form acidic solutions.
a basic oxide that dissolves in water is called an alkali
Metal oxides form alkalis when they dissolve in water. Non-metal oxides for acids. For example: carbon dioxide + water --> carbonic acid magnesium oxide + water --> magnesium hydroxide
Metal Salts + water
Metal oxides can be basic, acidic, or amphoteric depending on the metal and the oxidation state of the metal ion. Basic metal oxides react with acid to form a salt and water, while acidic metal oxides react with base to form a salt and water. Amphoteric metal oxides can act as both an acid and a base depending on the reaction conditions.
Metallic oxides are basic in nature, because when metallic oxide dissolves in water it forms corresponding base, which turns red litmus to blue.Those metallic oxide which dissolve in water are known as alkali, while those which do not dissolve in water are known as base
Non-metal oxides are compounds that contain a non-metal element bonded with oxygen. They tend to be acidic in nature and can react with water to form acids. Non-metal oxides play a role in atmospheric chemistry and can contribute to acid rain when they dissolve in water droplets.

Metal oxides react with acids to form salts and water. The metal oxide will typically dissolve in the acid to produce the corresponding metal salt and water as the product. This reaction is an example of a neutralization reaction.
Metals typically form basic oxides, which dissolve in water to form alkaline solutions. Nonmetals usually form acidic oxides, which can react with water to form acidic solutions. Oxides of metalloids can exhibit both acidic and basic properties.
These oxides are called amphoteric because they can dissolve in acidic solutions to form metal cations in the solutions but can also dissolve in strongly alkaline aqueous solution to form oxyanions of the metals: aluminate or zincate.
Metal oxides can act as bases because of their ability to accept protons. When metal oxides react with water, they can form metal hydroxides, which are basic in nature due to their ability to release hydroxide ions in solution.
