This is a series of chemical reactions involving potassium (K) and oxygen (O), leading to the formation of potassium hydroxide (KOH), potassium sulfate (K2SO4), and potassium chloride (KCl).

K reacts with O to form K2O.K2O reacts with water (H2O) to form KOH (potassium hydroxide).KOH reacts with sulfuric acid (H2SO4) to form potassium sulfate (K2SO4).K2SO4 reacts with hydrochloric acid (HCl) to form potassium chloride (KCl).
