How is the strength of hydrogen peroxide changed?
Water is added to decrease the Conc^
or the water is evaporated of to increase the Conc^
Does hydrogen peroxide lose its strength?
Hydrogen peroxide decomposes through a thermodynamically favourable reaction: 2H2O2 → 2H2O + O2 The rate of this reaction increases with temperature and depends on factors like its concentration, pH and the prescence of a catalyst. Thus, a bottle of hydrogen peroxide can decompose when stored under unfavourable conditions.
How fast does hydrogen peroxide solution break down?
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.
Liver plus hydrogen peroxide equals what and what?
When Hydrogen Peroxide (2H2O2) is combined with a small piece of liver, the hydrogen peroxide decomposes. This is because the small piece of liver acts as a catalyst, or the cause, of the decomposition of the Hydrogen Peroxide. The balanced equation is thus: 2H2O2 (Hydrogen Peroxide) ---------> 2H2O + O2
