Tip 1: How to grow crystals of copper sulphate

crystals always aroused human curiosity and a special surprise.Nature itself has taken care of the phenomenon of their growth, thereby forming beautiful crystals bizarre.It turns out you can grow crystals of copper sulphate alone even at home, especially as a reagent necessary for this purpose are so common that there is practically in every home.This copper sulfate hydrate crystals which has a blue color, and the anhydrous salt thereof - light blue.To grow the crystals are perfect both.
you need
  • glass, a plate or saucer, bluestone, clearcoat
Guide
1
buy copper sulfate or copper sulfate can be in any shop for repair or gardening, becauseas the appointment of a copper sulfate precisely spraying of trees and shrubs from pests.There is no need to use specialized glassware and all laboratory manipulations can be performed in a conventional cup and saucer.
2
first preparing primary brine.To do this you need to take half a cup of hot water and dissolve half a teaspoon of copper s
ulfate.After complete dissolution of the salt to dissolve repeated until it is no longer dissolve.Thus, a saturated solution of copper sulphate .
3
crystals to get a beautiful and clean, it is necessary to filter the resulting solution, and as quickly as possible until crystallization occurred.The resulting filtrate was poured into a glass dish and cover (you can not cover, but dust or insects into the solution it will happen as a result of pollution and the crystals lose their purity).
4
A day later, and perhaps sooner, we can already observe the precipitated small crystals.They appear a lot, some of them located clusters, and some - a single instance.This diamond-shaped crystals in the past and need to pay attention.For further work is necessary to select the most appropriate form of crystals without inclusions or other impurities.
5
Then again preparing a solution of copper sulfate , now called the mother, and in a similar way.The resulting filtrate was poured into a saucer or plate, and carefully put it in the selected crystals in an amount of from 2 to 5 pieces.An important condition is their remote location from each other, or at the time of its own growth, they can connect with each other and then form crystals will not work correctly.Then, close the container and glass from time to time to prepare a new stock solution and gently topped up to the previous one, in which the crystals are growing up.
6
After a few weeks, you can grow crystals of copper sulphate a beautiful diamond-shaped formations saturated blue.Only need to remember that the resulting product is very fragile and eventually loses water, turning into a loose powder blue - in the anhydrous salt, that is, in other words, is the destruction of crystals.And so in order to preserve their long covered with varnish.
7
Similarly, you can get a "miracle stone" on a string, if the first place the initially obtained crystals along the thread on the bottom of the dish.That will have personally made a necklace out of the blue "gems."The grown crystals can serve as a source of pride of their own achievements in the field of chemistry.

Tip 2: How to grow bluestone

Independently grow stone, jewel-like colors of the azure sky, can anyone - child and adult.
you need
  • - Glass jar
  • - Perekladinka wire
  • - Thread
  • - Required reserve sulfate vitriol
  • - Two weeks and patience
Guide
1
The first step is the preparation of a concentrated composition of copper sulfate.We must take the flask with water, put in her vitriol and mix gently.To understand when the salt solution is sufficient, it is necessary to watch closely, as it dissolves.If dissolution is no longer to occur, immediately stop the dilution.At three hundred grams of water usually have two hundred grams of vitriol.
2
Then take a pot, fill it with water (not to the brim) and put back the glass.The goal - a few warm-up, but no more.Watch carefully and stir.Should a concentrated lukewarm solution in which managed to dissolve all the vitriol.
3
Take a jar or cup and pour dedicated to the resulting liquid.Now we need to prepare so-called "seed."To do this, take a string and tie it to a small crystal of copper sulfate.Make perekladinku to secure the thread and put it on a glass, dropping a crystal in a solution.The solution should have time to time to cool slightly.
4
around this thread and will grow a crystal.Initially attached crystal dissolve - it does not matter.Next two ways: either grow a crystal quickly or slowly.In the second case, it is important to take the seed for a beautiful crystal (to get the same, only bigger).In this case it is necessary to remove the structure from the veiled banks perekladinki and thread in a secluded place, where there will be room temperature.And wait.About two weeks.Then enjoy the results.
5
If you want quick results, you need a solution again heated slightly lower thread again and something to cover bank.And then several times - from mild heating to cooling.Watch - a thread, when the solution is cooled down, the other will attach small crystals.If the result is a small pellet, it's okay.Hide the bank on the day.One day a handsome crystal is ready.
Note
- The same experiment can be carried out with the usual salt
- You can make a crystal of unusual shape - to wind the wire in a specific shape (eg, heart-shaped), and make sure that the crystal is nottoo grown to outlines were visible
Helpful Hint
- Copper sulfate can be purchased through the Internet, sometimes it can be found in hardware stores.
- Perekladinku can be done easily from the rod ordinary pen.
- If you want to keep the crystal, gently pat dry it, cut the thread and coat with varnish.
Helpful Hint
If you want to get a single, correct form crystals, then make sure that when topping up the solution to the main crystals are small crystals dropped new.
