What is the difference between hydrogen peroxide and alcohol, and what happens when hydrogen peroxid

Both can be sterilized and disinfected, but there is a difference, hydrogen peroxide can produce gas, the molecular formula H202, and the molecular formula of alcohol CH3CH2OH

Hydrogen peroxide can produce gas, the molecular formula H202, and the molecular formula of alcohol CH3CH2OH.

High concentrationHydrogen peroxideMixing with alcohol can happen**.

Medical alcohol. The concentration is 75%, if it is put together with a relatively high concentration of hydrogen peroxide, hydrogen peroxide is generally used in laboratories with 30%, and ethanol at this concentration.

Mixing should be fine, room temperature should not react. If it's 90% hydrogen peroxide, you have to be careful. So in life, we must pay attention to this situation.

Under normal circumstances, hydrogen peroxide is not very stable, stirring, light, heating will decompose it into water and oxygen, and add manganese dioxide.

It acts as a catalyst to increase the rate of oxygen production and can be burned with alcohol.

Although both have a disinfection effect, the action scenarios are different. One can be used for disinfecting wounds, but not alcohol, because it is very painful and can only be used to disinfect the unbroken epidermis.

Alcohol and hydrogen peroxide mix will bubble violently, the concentration of alcohol is diluted, the disinfection effect decreases with the degree of dilution, it is not recommended to apply this liquid to the wound, if you want to use these two liquids to disinfect the wound, you can first clean and disinfect the wound with hydrogen peroxide, wipe it dry with dry cotton fiber, and then wipe it with alcohol.

A mixture of high concentrations of hydrogen peroxide and alcohol can cause **, used as rocket fuel:

Hydrogen peroxide is catalyzed by manganese dioxide to decompose to produce oxygen, which burns with alcohol to produce large amounts of carbon dioxide and water.

Under normal circumstances, hydrogen peroxide is not very stable, stirring, light, heating will decompose it into water and oxygen, add manganese dioxide as a catalyst, increase the speed of oxygen production, can burn with alcohol.

Ethanol concentration is about 75% before disinfection, because 75% ethanol can enter the inside of bacteria, so that the proteins in the rotten part of the bacteria coagulate, thus killing bacteria and viruses. Hydrogen peroxide, on the other hand, has strong oxidizing properties and can use oxygen ions to destroy and break down bacterial proteins, but it must be diluted before use.

Ethanol and hydrogen peroxide have different compositions, so the principle of disinfection is also different. Ethanol can only be sterilized when the concentration is about 75%, because 75% concentration of alcohol can enter the inside of bacteria, so that the proteins inside the bacteria coagulate and kill bacteria and viruses, so 75% ethanol is also known as medical alcohol hunger.

The disinfection principle of hydrogen peroxide is that hydrogen peroxide itself is an active oxidant, and when hydrogen peroxide is used, oxygen ions will be released, and its strong oxidation will be used to destroy the proteins inside bacteria and viruses, so as to achieve the effect of sterilization and disinfection, so hydrogen peroxide and ethanol will be very different in disinfection.

When ethanol is used as medical alcohol, it must be diluted to a concentration of about 75% before it can be sterilized, otherwise other concentrations are useless; Hydrogen peroxide also needs to be diluted when used, because hydrogen peroxide has strong oxidizing properties and can be prepared by wearing plastic gloves to avoid corroding hands**.
