CHANGES OF DENSITY OF HYDROGEN PEROXIDE SOLUTIONS ON COOLING AND FREEZING
The densities of binary solutions of hydrogen peroxide and water from 0 °C. down to their respective freezing point were measured by the dilatometric method with an estimated precision of ± 0.0003 gm. per ml. Volume changes during solidification were also measured but with lower precision. Solutions containing less than about 50% by weight of hydrogen peroxide expand on freezing whereas more concentrated solutions contract appreciably. Various observations on the phenomenon of supercooling seem to indicate that no solid solutions are formed between the two components. Under certain conditions hydrogen peroxide solutions decompose on melting.
