Detailed Solution

Concept- Oxides are binary mixtures of two elements, oxygen and another. These oxides might have a neutral, amphoteric, acidic, or basic character. The neutral oxides have neither acidic nor basic characteristics.
Acidic oxides: These oxides produce acids when they are dissolved in water. These oxides are often non-metal oxides.
Basic oxides: These oxides produce bases when dissolved in water. These oxides are typically those of the elements in groups 1 and 2.
Amphoteric oxides: These oxides have dual acid-base reactivity. As a result, salt and water are produced when they react with a base (neutralisation reaction). Similar to how they create salt and water when reacting with an acid.
Oxides that are neutral: They don't have acidic or basic characteristics. When they interact with an acid or a base, they do not produce salts as amphoteric oxides do.
