How fast does hydrogen peroxide solution break down?

Answer 1

This depends on a variety of factors such as temperature, the strength of the hydrogen peroxide solution and the presence or not of a catalyst, like manganese dioxide or silver. Acidic solutions also exhibit better stability. So, a slightly acidic and weak solution of hydrogen peroxide, stored in a cool place, will break down the slowest. Hydrogen peroxide decomposes to form water and oxygen, liberating heat in the process.

Answer 2

Hydrogen peroxide typically breaks down into water and oxygen within minutes to hours, depending on factors such as concentration, temperature, pH, and the presence of light or catalysts. Higher concentrations and warmer temperatures can accelerate the decomposition process.
