In separate containers, add a little bit of yeast to the bottom. Pour the liquids into the yeast. The one that bubbles up and gets warm is the hydrogen peroxide.

The difference in sp gravity at normal temperature of H2O2 being 1.452 and of normal water 0.9998 can differentiate by density/*** sp gr hydrometer, slight light shade og blue will be observed with a bottle of H2O2 where in white transparent in case of normal water when they are placed under day light.Normal water on heating at NPT will start boiling at 100C but a sample of H2O2 will not boil at 100C but on further heating it would boil at 152 C around and release continuous bubble within dur to release of O2 . Do not undertake any unsafe method for testing and analysis which may be risky , like catching flame , explosion, etc.
