Home Experience With Water
O.Olgin. Explosive experience
Once a man started cooking his food, he became a chemist. Large chemistry and biochemical processes were followed in steam and heat, barrels and clay vessels. By the way, not all of them have received a full explanation and today, which, however, does not prevent people from barking, stooling and grading. However, much has been studied. And something - of course not the hardest - can be replicated even in the home lab.Experiences in this section have at least one undeniable dignity: the necessary substances (previously products) will be found in the kitchen closet or in the refrigerator. Or they can be bought in a food shop. You're going to need a small number of substances, but if you buy a product more than you need for experience, the rest will not be gone.
The most important part of the food is white, the foundation of all the living, the building material of all the organisms. Thousands of researchers around the world work with a protein, study its properties. Of course, in our experience, we won't open anything new. But it's said that the trouble is beginning... The first experience is a qualitative response to the squirrel, that is, a reaction that will allow us to know whether the white is before us or not. That's a few reactions. The one we're going to run is called a biuret. For her, we're going to need washing soda solutions (or edible soda) and copper corn.Prepare a few solutions that can be assumed to contain protein. May it be a meat or a fish bulb (preferably healed through a marble), or any vegetable or mushroom or other.
You're gonna have to put your trackers around half. Then add a little solution to the brush-- meal or laundry soda. Finally, add a blue copper corn solution. If there's a squirrel in the test chef, then the paint will be purple.These reactions say they're characteristic. They only go if there's a squirrel in the solution. For control, please. Lemonade experience or mineral water.
Everyone knows that when heated, the squirrel is cutting off and moving into an intact shape, the raw egg is getting cool. It's called protein denaturation. Every owner knows to make a delicious boulon, you have to put the meat in cold water. And when they want to cook the weld meat, the big pieces fall into the boils. Does that make any sense? Let's try to figure it out.
Put some cold water on, put some raw roasted meat in it and heat it. As heating occurs, gray cereal is formed (and in large quantities). It's a twisted squirrel, a foam that makes noise so that it doesn't spoil the view and taste of the bulon. Continuing heating, water-soluble substances are gradually moving from meat to solution. These substances are referred to as extraactive because they are extracted from meat when extracted by boiling water (simply to say, in a bulon barrack). They're, first and foremost, giving the boulon a typical taste. And the meat, being removed from these substances, becomes less delicious.
The squirrel shall be denaturated not only when heating. Put a little fresh milk in the sample and drop one or two ounces of oxy or a lymone acid solution. Milk's gonna squeeze like white cereal. It's cutting the dairy squirrel. By the way, without such a reaction, don't make a creativity, and not by accident, the creativity is so useful, it's almost all milky white.
When the milk is left in a warm place, its protein is also cutting down, but for a different reason, it's a milk bacteria. They know a lot, and they all produce dairy acid, even if they don't eat milk, but, say, cable juice. Fix a little skinny milk and add a few drops of some improvised indicator to the serum. The color of the indicator will show that there is acid in the solution. This acid is dairy, it can be detected in cabbage and in an ogre.
Some white molecules include, in addition to carbon, hydrogen, oxygen and nitrogen, and sulphur. You can learn from experience. A little egg squirrel will be placed in a dried soda solution or a washed soda solution and, by heating the sampler, add a little lead acetate solution Pb(CN3SOO)2. 3H2O is a lead-in-belt that is sold in pharmacies. If the contents of the test tube are black, then the sulphide is PbS lead, the black substance.
