Catalytic decomposition of hydrogen peroxide (aka - elephant's toothpaste, Old Foamy)

[@emaniwilliams5936]

The answer for those in chemistry. Initial Appearance: 35% hydrogen peroxide along with dish soap in a tube with hydrogen peroxide. Observation: There is a tube with 35% hydrogen peroxide and dish soap gets pour and mixed with the 35% hydrogen then a catalytic get poured into the tube making a foam like substance come out of the tube. Type of change: chemical change. evidence: The 35% hydrogen and the dish soap along with the catalytic make a foam substance come out of the tube.

[@Sedokun]

Hydrogen peroxide is a cytotoxic agent (meant to destroy cells completely, compared to acid it may cause an effect of 'oxidative stress'). "H2O2, a highly reactive agent, can react under certain conditions with a variety of cellular components. These reactions include the lipid peroxidation of membrane and hydroxylation of proteins and DNA. The reactions can take place in the presence of oxygen and are fairly rapid, the H2O2 being converted to water and oxygen. Experiments were carried out in vitro to assess the ability of this agent to destroy cancer cells without generating dangerous by-products. The direct administration of aqueous H2O2 into solid tumors has the potential to cause tumor cell death."

[@magnumopusproductions4043]

Finally someone who understand it! And also H.P can kill any type of organic matter when it react with iron which produce Hydroxyl radical which is highly reactive and then at time of this thing produce any organic matter to come in contact with it will eventually be dead and assured. That's why bacteria which use a lot of iron can't make it in the people's body where H.P is abundant (I think)

OBSERVATIONS: At the end the liquid’s is gone and there is a thick kind of paste that is red and blue from each liquid. At first it rises and then it goes down. TYPE OF CHANGE: Chemical change

Maybe it doesnt clean wounds, but it's definitely a biocide and can be used to sanitize surfaces. You still shouldnt use it to disinfect your wounds though, because it doesnt just kill bacteria, it also kills the human cells, which slows down healing (which means a higher risk of infection and more scarring).

[@matthewcurry3565]

Nahhhh I use 3% all the time, and it works very well. Reduces the war for your body to fight. Especially because you can't actually see what viral loads, or bacteria strains got in.

a little confused on what role the soap plays. I thought the oxygen was stored in the peroxide itself and that a O2 was released as the peroxide converts to water.

I think i get it. the soap traps the bubbles from bursting and releasing the O2 into the surrounding air.

soap makes the foam i think
