The science behind how hydrogen peroxide works to target stains and make whites brighter once again ties back to its interaction with the color-forming component in the stains' chemical structure.

Add 30mL of 30% hydrogen peroxide with stirring. Point out that the reaction is proceeding very slowly if at all (no gas bubbles visible). Pour 50mL of 0.4M cobalt chloride solution into a beaker to ...

The scientists utilised a zinc-air battery in which oxygen reduction generates H2O2. “Zinc is an abundant and historically used element.
