REFRACTIVE INDEX OF HYDROGEN PEROXIDE SOLUTIONS. A REVISION

Author:

Giguère Paul A.,Geoffrion Pierre

Abstract

Values for the refractive index of aqueous solutions of hydrogen peroxide reported some years ago by the senior author have been found in error by more than the estimated accuracy of measurements. The error is proportional to the concentration of the solutions and amounts to about 5 × 10−4 for the pure peroxide. More accurate data have now been obtained by using an instrument of higher precision and by refining the analytical method. In addition, some anhydrous hydrogen peroxide has been prepared; its refractive index at 25 °C. was 1.40672 ± 0.0001 with an average temperature coefficient of 3.4 × 10−5 per degree.
