Buy a bottle of toilet cleaning spirit , and you can make many beautiful crystals . The main ingredient of

Toilet Cleaning Spirit is hydrochloric acid, and it also contains a small amount of pigment, which can dye some colorless crystals light blue.

and most of the compounds containing chloride ions are good-looking and easy to prepare, so we choose toilet cleaner as the reactant ( sodium chloride potassium chloride is not good-looking, aluminum chloride zinc chloride is difficult to crystallize , Magnesium chloride is easy to weather.

Calcium chloride : First, pick up a stone from outside, not cement bricks, but paving stones.

Put the stone in a cup, pour the toilet cleaning spirit to dissolve, and you will get a calcium chloride solution. Collect a large amount of solution, preferably more than one kilogram, and evaporate naturally under dry conditions, you can get large crystals

as shown:

(blue is the pigment of toilet cleaner, real CaCl2·6H2O is white and transparent

Cobalt chloride :

Make a white magnet and add too much white vinegar first. It will bubble and precipitate a lot of powder. These precipitates are cobalt powder . After the precipitation is stable, filter out the upper liquid and then clean the toilet. If you continue to heat it, the cobalt powder will bubble and dissolve, and you will get a compound called cobalt chloride, which is pink.

Then just wait for it to crystallize. Above,

Copper chloride : Find some thin copper wires, the same. It's a toilet cleaning spirit. Just take a piece of pencil lead , wrap the copper wire around it, and soak it in it. It also requires a large amount of solution concentration to get large pieces. Put more iron nails under it and put oxidized neodymium chloride . Neodymium magnets add a small amount of toilet cleaner (the reaction is violent and difficult to get. Many neodymium magnets on the Internet are Fake goods)

That’s all chloride that can be obtained in life. The most common ones in sulfate are sodium sulfate and copper sulfate, but copper sulfate is not actually a good-looking crystal, and the color is too dark. Sodium sulfate can be purchased directly. The crystals are very beautiful, but they are easy to weather and will fall apart into white powder.

I once stored it in a sealed bottle, but the surface still turned white after a week. ↓

Elements: sodium, Cesium, antimony, tellurium, and arsenic are more beautiful to look at, but the preparation method is more difficult. I only show the picture

. Then add the copper rust that grows out of the copper wire in the salt water.
