Nitric Acid + Potassium Oxide gives what salt?
Nitric Acid + Potassium Oxide gives what salt? And what is the chemical equation?

Potassium oxide is the basic anhydride of KOH. So nitric acid reacting with solid K2O would produce a "salt" and water. But you don't actually get the salt until the water is evaporated and the KNO3 is allowed to crystallize. What you actually get are a mixture of potassium ions and nitrate ions.
K2O(s) + 2HNO3(aq) --> 2KNO3(aq) + H2O(l)
K2O(s) + 2H+ + 2NO3- --> 2K+ + 2NO3- + H2O(l)
The net ionic equation is
K2O(s) + 2H+ --> 2K+ + H2O(l)
K2O must be in the solid state initially, not K2O(aq), because if K2O solid is added to water it will immediately react with the water to make K+ ions and OH- ions.

HNO3 +K2O --> H20 + KNO3
The salt is potassium nitrate.
To balance the equation: 2HNO3 +K2O --> H20 + 2KNO3

2HNO3 + K2O → 2KNO3 + H2O
Potassium nitrate is formed.
