The answers to those chemistry experiments have long been known to professionals, but some things can be checked in the “home lab“. It is necessary to “sacrifice” two boxes (every 50 grams) of Green Tea, one can also use Black Tea, but it is not the best.  by the way, there is lots of tea available nowadays Like matcha tea, chamomile tea, oolong tea, hibiscus tea, rooibos tea, ice tea, black tea, chai tea, silver queen green tea etc.

The leaves of the tea contain catechins substance – candidates, as well as gelatin catechin esters. For example, excellent teabags contain epicatechin-gallate and gallocatechin-gallate, which are organic compounds with complex structures. There are more green teahouses, so it is more appropriate to use Green Tea for our experience.

EXPERIENCE 1: Green Tea Shots Recipe

In a 1.5 liter pot of metal enameled pot, fill 100 g of green tea, add 200 ml of hot water and boil for about an hour. The solution is filtered by double-sided cotton fabric and washed with 200 ml of hot water over the fabric.


In the light green solution obtained, add 35 g of lead acetate Pb (CH3COO)2. The latter is also known as “lead sugar” because of its very similar to sugar, but it is very toxic and cannot be tasted. The substance is clarified and washed several times with hot water (300 ml each time) until full removal of Pb2+ ions. Pb2+ takes a few ml to dissolve the ions of the ions, adds a small solution of sulfuric acid in the test, and if white precipitate occurs, it means that Pb 2+ is not completely removed.

Lead sludge is filtered with glass cotton and then washed with 50 ml of 1% solution of sulfuric acid. The filter fills in a chemical cup and checks the presence of excess ions in the BaCl2 solution. If they are present, they are drop-by-drop by adding Ba (OH)2 to a 5% solution and cleansing BaSO4 sludge.

The remaining transparent solution evaporates to a water bath until drying. The bottom of the cup remains the home of the tea. It can be pulled to powder and kept in a dark glass bowl tightly closed with a cork. The exit of tahini is 5-7 grams. Experience with silverqueen green tea.

Experiment 2: benefits of green tea

40 ml water solution of 0.5 g of lead and pour a few ml FeCl 3 in solution. the black greenish coloration of the solution is observed. This solution is nothing but ink. The ink used for writing was still used in ancient times.

The test is filled with 0.3 g of additive and adds three drops of dense hydrochloric acid. is obtained from the red color floofen, which is the condensed product of various counteracting derivatives and their derivatives.

0.3 g of vanilla is dissolved in 0.2% solution of nitric acid and adds 0.1 g of carotene. Immediately notice the reddish-brown color of the mother. This is one of the most characteristic reactions to the Cretans’ detection.

And finally, a lipstick pencil that contains silver nitrate sold in pharmacies is soluble in 40 ml of water and adds 1 g of tin to it. comes from gray sediment on a silver bull.

Experiment 3: Cold Tea

Tea leaves also contain caffeine, due to which strong tea has a refreshing effect. Caffeine is an alkaloid (alkaloids derived from the Arabic “alkali” basis and from the Greek word “eidos“, meaning the basis of alkaloid).

Alkaloids have plant origin, have weak basic properties, and therefore interact with acids causing salts.

Mix one teaspoon of black tea and 2g of MgO in a mortar with a crunching trowel and transport in a fur coat so that it can hold 1/3 of the solvent. Then place a glass bowl filled with cold water on the salad and carefully heats the solder on the spirits. Caffeine is exhausted and thickened on cold walls of a glass bowl in the form of glossy crystals, which can be collected in a clean bowl.

Experience 4: Caffeine’s Qualitative Reaction

In a small paste, fill in a small amount of caffeine, add 2-3 drops of concentrated nitric acid and carefully evaporate to dryness. With the effect of nitrous acid, caffeine is oxidized and resulted in orange gum pickles. If we add ammonia to this acid, a dark red residue that is called salt, called mouxid, will emerge. This reaction is known as Caffeine Mouxidine Reaction.

In addition to these substances, tea leaves also contain essential oils, vitamins, carbohydrates, and other useful substances. chemistry experiments

Why Is Our Body Temperature 36.6 oC?

A very unique and interesting version is offered on this occasion.

It is known that chromium suddenly changes its heat, elasticity module, specific electroconductivity, linear thermal expansion. At the same time, these changes occur not at the absolute zero temperature or in the red lighting of the metal, but at the normal temperature of the warm body.

This coincidence leads to the hypothesis that explains why the normal temperature of the body of a wide range of warm-blooded animals is 37.8 o C on average, with a deviation of 4-6 degrees, whereas the temperature range above the globe is greater than the temperature.


It seems that in the evolution period, for the inhabitants of the cold regions, a certain value of normal temperature should be established, and for the inhabitants of the equatorial regions, which would be logical from the point of view of the minimum energy consumption required for vital activity.

However, this is not the case with living things, which causes the surprise of the experts.

Every time there is no convincing reason, there are hypotheses, one of which is the so-called “chromosomal version“, which is based on the chromium “deviated” properties and the average normal temperature of the body of hot-blooded animals (about 37 oC).

Chromium is one of 50 microscopic proteins found in DNA and lipids. In nature, it is widespread and scattered, and animals and people get enough of it with food. chemistry experiments

And that’s what matters. There is widespread information that the chromium content in the body of the hot-blooded animal is much greater in the body, where the temperature changes from contact with the environment, and in well-isolated internal organs, such as hypophysis, in the larynx, lungs, and intestines, it is small.

why chromium?

It is possible that, indeed, the chromium has become a crucial role in the evolution of the thermocouples and nerve limbs that collect information about the change in the heat flow of the organism.

Is not this the warmth of the body of warm animals? The “chromium hypothesis” can be explained by the high sensitivity of the thermocouples.

And indeed, can not this hypothesis be explained by a drastic change in the properties of chromium in a small range of temperature fluctuations?

The Crucial role in evolution:

Is this feature of chromium not used in snakes’ “thermocouples” located in the middle of the nostrils and eyes? The glowing snake’s “thermostat” is capable of responding to the fluctuations of the hundredth part, which enables mice to catch the night. chemistry experiments

Is not the so-called “thermocouple” receptor responsible for chromium particles concentrated in nerve tissue?

Modern analysis methods detect an arbitrary microscopic preparation if its content is smaller than 10-12 grams. In this regard, it would be extremely interesting to look at human and animal heaters, and especially the “snakes” of snakes. The high content of chromium in these tissues compared with the small amount of chromium in other non-heat-sensitive tissues may be the basis for the approval of the “chromosomal version“.
