Sulfur Dioxide And Sulfurous Acid (1959)

Discusses the chemistry of sulfur compounds, particularly focusing on sulfur dioxide (SO₂) and sulfurous acid (H₂SO₃). It explains the oxidation states of sulfur, the methods of preparing sulfur dioxide, its properties, and reactions, including its role as a reducing agent and its solubility in water. The text also describes experiments demonstrating the formation of sulfurous acid, the reaction of sulfur dioxide with water, and its use as a bleaching agent. Additionally, it covers the oxidation of sulfite ions and the reactions of sulfur dioxide with hydrogen sulfide, leading to the formation of elemental sulfur.

Keywords:
sulfur, sulfur dioxide, sulfurous acid, oxidation states, reducing agent, solubility, chemical reactions, bleaching agent, sulfite ions, hydrogen sulfide, preparation methods, experiments, acid-base reactions, sulfate ions.
