About this book

The Reaction Between Manganese Dioxide and Potassium Permanganate is a dissertation presented for the degree of Doctor of Philosophy to the Board of University Studies of the Johns Hopkins University by Arthur John Hopkins in 1893. The acknowledgment says the work recorded in the paper is the result of a suggestion given by Professor H. N. Morse. A section is headed The Reduction of Neutral Potassium Permanganate by Manganese Oxide at Ordinary Temperature.

The text says three 250 c.c. portions of each of the solutions A and B were placed in clean glass-stoppered bottles. The text says that to one bottle was added 0.5 gram of the manganese oxide, and that an analysis on October fourteenth showed that its strength had declined 34.62 percent. The text says results are expressed in the table following in terms of oxygen atoms obtained from each molecule of potassium permanganate reduced. The text says it is clear that the rate of the reduction of the permanganate is greatly increased by increasing the quantity of the manganese oxide.
