What type of salt is MgO?

Magnesium oxide (MgO) is not a salt in the traditional sense but rather an ionic compound formed from magnesium and oxygen. It is classified as a basic oxide, which means it can react with acids to form salts and water. In a broader context, it can be considered a type of salt because it results from the neutralization reaction between magnesium hydroxide and an acid, but it is primarily known for its properties as an oxide.
