Hydrogen experiments for kids 1: Hydrogen peroxide kills blood

While experimenting with the General Warning observed.

Hydrogen peroxide is formed in many reactions of oxygen in the blood. Because it is toxic, the body has developed a greatantidote. That is, catalase, and is present in blood. So you canmake a nice experiment.

Safety Note: Hydrogen is explosive in high concentrations andwhen heated. In addition, it is corrosive. therefore:
Experimenting with hydrogen peroxide you can only under adult supervision!
Working with protective goggles and gloves. If you still getsome solution to the skin, then stain the white spot in the short term, and it burns a little. Rinse well with water. Soon the pain is forgotten, the site continues to heal immediately.

Give about 50 milliliters of hydrogen peroxide in a tall glass, preferably in a wheat beer glass. This will you give 100 ml ofblood, did you get from the butcher.
The mixture foams immediately on strong. The whole looksalmost like a delicious sundae. You must try not to!
But the blood did not change obviously, because it is still as beautiful red.

They say that a substance that causes a reaction without beingchanged or consumed, is a catalyst. Here is a catalyst that actsin biological material.
We call such biological catalysts enzymes.

Hydrogen experiments for kids 2: Hydrogen peroxide bleaches colors

While experimenting with the General Warning observed.

If someone has bright blond hair, he is told to love, he would have used to lighten the chemical hydrogen peroxide. That may be true sometimes.

If you should try some, discolour your hair itself, necessarilythink the following: Commercially available hydrogen peroxideis a 30-percent solution and much too concentrated. If you want to dye your hair, you have to dilute the solution to at least 1:10.So let put your fingers on it and ran a hair better … He knows what he’s doing. And if he builds crap, you can sue him!

Safety Note: Hydrogen is explosive in high concentrations andwhen heated. In addition, it is corrosive. therefore:
Experimenting with hydrogen peroxide you can only under adult supervision!
Working with protective goggles and gloves. If you still getsome solution to the skin, then stain the white spot at short notice and it burns a little. Rinse well with water. Soon the painis forgotten, the site heals quickly.

The bleaching action of hydrogen peroxide has the addition of alkalis to the assumption. The hairdresser takes ammonia, orhe took it at least once. Ammonia is highly corrosive. We dotake this dangerous substance to some soda solution.

Site 5 ml of a 10 percent solution of sodium carbonate ago.(That’s half a shot glass full.) In a small jar you give to 10 ml of 3% hydrogen peroxide. Then you throw into a tuft of dark hairand press the hair into the liquid to moisten it completely.
Let stand overnight. Rinse the hair thoroughly and dry them.

Hydrogen experiments for kids 3: Detection of hydrogen peroxide by catalase

While experimenting with the General Warning observed.

Devices: 3 test tubes, test tube rack, pipette dropper.

Chemicals: A raw potato, boiled potato, hydrogen peroxide solution (w =3%) (C), catalase solution (w = 1%).

Implementation:

Abundance of each of the three test tubes about one-quarterwith hydrogen peroxide solution. Be moved now, the first Test tube with a piece of raw potato, the second Test tube with a small piece of boiled potato and the third Test tube containing a few drops of catalase solution.

Result:
In the first and 3 Test tube is to observe the formation of gas.The detection of catalase positive.

Hydrogen experiments for kids 4: Fehling sample with hydrogen peroxide

While experimenting with the General Warning observed.

Devices:
Water (400 ml), water heating device for test tubes orErlenmeyer flasks (25-50 ml), Glimmspan.

Chemicals:
Fehling’s solution, hydrogen peroxide (w = 30%) (C).

Implementation:
We mix 5 ml and 5 ml of Fehling Fehling I II at a large test tube (or a larger amount in a small Erlenmeyer flask) and ask thedeep blue solution for heating in a boiling water bath. After a few minutes we pass gradually dropwise until hydrogen peroxide solution (w = 30%) (C) in until the reaction mixturebegins to significantly and permanently change the color.Caution! The mixture foams.

We also carry out the glowing splint.

Result:
In the solution formed when careful instillation of H2O2 gasdevelopment with strong yellow-brown copper (I) hydroxide,which dissolves again, however. Only after repeated addition ofH2O2 solution, we get consistent, deep red copper (I) oxide.This sets off when we leave the reaction mixture.
The gas we identify as oxygen.
