Growing crystals at home

If you are fond of various experiments in the field of chemistry, then as a hobby we suggest you try to grow crystals at home. This is very interesting, when out of nothing in your eyes grows different crystal splendor, 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 a slow speed means the formation of a large crystal, and vice versa: the faster the process, the smaller the size of the crystals formed.

Growing a crystal at home can be various 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 pan 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 act 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 excess 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 the dimensions that you expect. Repeat the procedure again, you can increase the crystal size to infinity.

Thus, you can grow crystals at home from any salt. 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 water 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 the red crystals in the home are obtained in 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 putting a bit of copper sulfate evenly on the bottom of the glass, pouring salt on top and this mixture is covered with a mug of a blotter on which buttons or a steel plate are placed. Then on all the contents you need to pour to the top of a 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 home is possible and 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.
