Answer:
Sodium hydroxides
Step-by-step explanation:
Sodium oxide reacts violently with water to produce sodium hydroxide solution.
The reaction is shown below;
Na₂O + H₂O → 2NaOH
Chemical reactions like this produces an alkaline. The product NaOH is strong alkaline solution that completely ionizes in solutions.
When a metallic oxide combines with water, they produce basic solutions.
