The solubility of hydrogen peroxide was measured in concentrated salt solutions of ammonium sulfate, ammonium nitrate, ammonium chloride, and sodium nitrate at 19°C. Effective Henry's Law constants are reported for these salts for concentrations from 1 M to 10 M. Measurements at 13°C were obtained for several solutions to validate the experimental approach used and the temperature dependency of the Henry's Law constants. Hydrogen peroxide concentrations ranging from 2.0 x 10-3 M to 1.0 x 10-1 M were used in this study. Henry's Law constants determined in this work for hydrogen peroxide in pure water are (1.26 +/- 0.06) x 105 M atm-1 and (2.1 +/- 0.2) x 105 M atm-1 at 19°C and 13°C respectively. Salts containing ammonium ions were found to increase the solubility of hydrogen peroxide by up to a factor of two compared to pure water, but in sodium nitrate solutions the solubility decreased with increasing salt concentration.
