We are all magic tricks. Many of us know some simple tricks that can surprise our friends during a party or show our children and make them laugh. Today we will do a kind of chemical experiment, which can also become a beautiful focus.
Let's watch the video first thing:
So, in order to prepare our miracle liquid, you may have to go to the pharmacy, but we assure you - it's worth it.
We will need:
- Two glasses of the same size;
- Two small glasses (can be made of plastic);
- A container in which we pour warm water;
- A spoon with which we will mix;
- Potato or corn starch;
- One gram of vitamin C;
- Tincture of iodine;
- hydrogen peroxide (3%);
- Syringes for more accurate dosing of all components.
If vitamin C is in the form of tablets, then they must be crushed into powder. First of all, we need to add a gram of vitamin in a plastic cup and add 60 ml of warm water.
Next, we begin to stir so that the powder is completely dissolved in water.
The next step is to prepare liquid starch by mixing one teaspoon of starch in 150 ml of cold water. Next, add another 150 ml of hot water and stir well.
We take two identical glasses and fill them with 60 ml of warm water.
In the first glass, add 5 ml of tincture of iodine and 10-12 ml of liquid with vitamin C. After adding liquid with vitamin, iodine is completely discolored.
In the second glass add 15 ml of hydrogen peroxide and 7 ml of liquid starch.
The preparatory phase is over, which means that you can move on to the focus itself. We take glasses and pour the liquid from one to another.
After that, we need to put one glass on the table and wait. The liquid will soon change its color to dark. In chemistry, this experiment is known as iodine clock. If the essence of the experiment is described in the most accessible way possible, then we can say that this is a kind of confrontation between starch, which turns iodine into a dark liquid and vitamin C, which does not allow this to be done. In the end, the vitamin is completely consumed and the fluid instantly changes color. The magic was a success.By the way, if you add a little more vitamin C powder to the dark liquid, then the liquid will again discolor for a while.
