Question

Which of the following isn’t a basic oxide?

(a) Sodium oxide (b) Magnesium oxide (c) Sulphur dioxide (d) Calcium oxide​

Answer 1

Answer:

Sodium oxide is a simple strongly basic oxide. It is basic because it contains the oxide ion, O2-, which is a very strong base with a high tendency to combine with hydrogen ions. Sodium oxide reacts exothermically with cold water to produce sodium hydroxide solution.
