Growing crystals at home

If you are fond of different experiments inchemistry, then as a hobby we suggest you try to grow crystals at home. This is very interesting, when out of nothing in your eyes different crystal splendor grows, surprising with the perfection of shapes and color solution. You just need to know that growing crystals at home requires a lot of time, the process of crystal formation is not always fast. But as a result, it turns out that slow speed means the formation of a large crystal, and vice versa: the faster the process, the smaller the size of the crystals formed.

Grow a crystal at home can bedifferent ways. Among them: a decrease in the temperature of the substance, the evaporation of excess liquid from the solution. In order not to be unfounded and give practical advice on how to grow a crystal at home, we start with the simplest substance, with table salt. So, take a glass, pour water into it and put it in a pot with tap water, heated to about 50-60 degrees. Pour salt into the glass and leave for 5 minutes to dissolve. Think about how you will maintain the temperature of the water in the pan, because it needs to be constantly warm. So you do it several times until the salt ceases to dissolve. 100 grams of water requires at least 35 grams of salt. As a result, you will get a saturated solution, which must be poured into another transparent dish, making sure that it does not get the excess of dissolved and not dissolved salt. Now find some more or less large salt crystals, tie it in a string and hang it like that. so that it does not touch the walls of the glass. And all, it remains to wait a few days. While the crystal will not accept those sizes, which you expect. Repeating the procedure again, you can increase the size of the crystals to infinity.

So you can grow the crystals inhome conditions from any salts. From copper sulfate it is possible to obtain both blue and red crystals. In the same way as in the above process, you get a saturated solution of this salt. Only tap water will not work. You'll have to worry about getting distilled somewhere, because you can not get a clear solution of copper sulfate otherwise.

And red crystals at home receivein the following way. You will need copper vitriol, salt, blotting paper, cut in the form of a section of the tank and the usual buttons. This growing of crystals at home begins with the fact that a little bit of copper sulfate is placed evenly on the bottom of the glass, the top salt is poured on top and this mixture is covered with a mug of a blotter on which buttons or a steel plate are placed. Then, on the entire contents, pour to the top of the saturated solution of table salt, prepared in advance in the manner described above. Put this dish where it can not be moved for about one week. And then you will see how beautiful red needle-shaped crystals will grow.

Growing crystals at homepossibly in a multi-layered color form. For this, alums are needed, from which saturated solutions are prepared, in which various crystals are grown. And then they are alternately transferred from one solution to another. This is already a more complex process, for the implementation of which you need to have some knowledge in the field of chemical science. First, alum is dissolved at a fairly high temperature. Secondly, when stored in air, they can evaporate. Therefore, the results of growing such crystals can also be negative. So to such experiments it is necessary to proceed only in the event that you are not afraid of disappointments.
