Question

Write the equation for the reaction between potassium oxide and:

(i). Hydrochloric acid
(ii). nitric acid
(iii) Sulphuric acid

Answer 1

The equations for the reaction of potassium oxide with hydrochloric acid, nitric acid, and sulfuric acid produce potassium chloride, potassium nitrate, and potassium sulfate, respectively, along with water.

Step-by-step explanation:

When potassium oxide reacts with different acids, neutralization reactions occur, forming water and a salt. The reaction equations for potassium oxide with different acids are as follows:

• (i) Potassium oxide with hydrochloric acid:
  
  K₂O + 2 HCl → 2 KCl + H₂O
• (ii) Potassium oxide with nitric acid:
  
  K₂O + 2 HNO₃ → 2 KNO₃ + H₂O
• (iii) Potassium oxide with sulfuric acid:
  
  K₂O + H₂SO₄ → K₂SO₄ + H₂O
