They form bases.....for eg CaO+H2O---->Ca(OH)2
Most metal oxides are basic in nature because they tend to react with water to form metal hydroxides, which are alkaline solutions. However, some metal oxides can exhibit acidic properties when dissolved in water, such as oxides of non-metals like sulfur.
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.
Metal oxides typically produce basic solutions when dissolved in water, while nonmetal oxides usually produce acidic solutions when dissolved in water. This is because metal oxides react with water to form hydroxide ions, increasing the pH, whereas nonmetal oxides react with water to form hydronium ions, decreasing the pH.
Acidic oxides react with water to form acids, while basic oxides react with water to form bases. Acidic oxides have a higher concentration of oxygen ions, leading to a more acidic solution when dissolved in water. Basic oxides have a higher concentration of metal ions, resulting in a more basic solution when dissolved in water.
Most nonmetallic oxides react with water to form acidic solutions. The reaction typically produces an acid by combining with water to form a compound that releases hydrogen ions when dissolved in water.

Non-metal oxides are often referred to as acidic oxides because they produce acidic solutions when they are dissolved in water. These oxides are typically formed by non-metal elements combining with oxygen.
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.
Metal Salts + water
NO2 is a non-metal oxide. Nitrogen dioxide (NO2) is composed of nitrogen and oxygen, both of which are non-metals on the periodic table. Non-metal oxides typically form acidic solutions when dissolved in water, as they react with water to produce acids. In contrast, metal oxides tend to form basic solutions when dissolved in water.
Generically, they are called "rime". Primary constituents are salt, with other solutes being metal oxides and such.
Most nonmetallic oxides react with water to form acidic solutions. The reaction typically produces an acid by combining with water to form a compound that releases hydrogen ions when dissolved in water.
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.
When oxygen combines with metals, it forms metal oxides. Metal oxides are compounds that contain oxygen and a metal element. Examples include rust (iron oxide) and copper oxide.
