This publication primarily examines the chemical reactions between manganese dioxide and potassium permanganate, specifically focusing on the conditions and outcomes of these interactions in various chemical environments. The dissertation meticulously details a series of laboratory experiments designed to explore how manganese dioxide influences potassium permanganate, particularly in the presence of nitric acid. Hopkins utilizes specialized apparatus to collect and quantify the oxygen gas evolved during reactions, indicating the reduction of permanganate to manganese dioxide. The findings reveal that manganese dioxide effectively reduces potassium permanganate, releasing a consistent amount of oxygen, with the rate of reaction varying significantly depending on the solution's acidity. The work ultimately provides valuable insights into the chemical behavior of manganese compounds and their stability, as well as their interactions under different experimental conditions.
