Question

Quizplus · Accepted Answer

The acidity of binary oxides depends on the electronegativity difference between the elements. In general, the higher the electronegativity of an element, the more acidic the binary oxide it forms will be. Among the choices given, phosphorous (P) has the highest electronegativity and therefore forms the most acidic binary oxide.
