Copper acetate crystals at home
Good afternoon! Surely you have heard about growing crystals at home from all sorts of reagents: ferrous or copper sulfate, salt, citric acid. The color of the crystal depends on the reagent. This time we will grow beautiful black crystals of copper acetate.But first, let's get copper acetate itself (and our crystals will grow in the resulting solution).We leave the solution for a week. During this time, small crystals will start to form in it.
So, we will need:We also need disposable dishes: cups, spoons, - and several filters: coffee or, preferably,chemical.And pour half the distilled water. Stir until complete dissolution of the substance.Now in small portions (slides on the edge of a spoon) add soda. Immediately after the addition, you should cover the glass with a napkin, because as a result of the reaction, carbon dioxide bubbles are released, which carry particles of a solution with them. The reaction equation is shown below.And this is how the solution "sizzles":When carbon dioxide stops being released, you should stop adding soda and let the solution stand for a while. As a result, a transparent layer of the solution is formed from above:Then pour the liquid into another cup (it’s not for usneeded) and wash the precipitate of basic copper carbonate. To do this, add to it a little distilled water, mix, let stand and drain the liquid. This procedure must be repeated two or three times. Next, add distilled water to the substance again and pass the solution through the filter: we need to collect sediment. Once we have filtered the precipitate, it should be washed a couple of times on the filter. To do this, add water and mix it slightly.After that, directly with the filter, put the precipitate on a napkin so that it is slightly dried.When the precipitate dries, transfer it to a new cup. Next we need vinegar. It is added to the solution in small portions until all the precipitate is dissolved. Reaction equation:The solution becomes dark blue.The precipitate, like copper acetate, has a rather low solubility, because of this it is not very soluble when vinegar is added.When the precipitate dissolves, filter the solution. The filtered solution has a beautiful dark blue color.
It will take
So, we will need:
- Copper sulfate is a fertilizer sold in stores for the summer;
- Baking soda and vinegar 9% can be found in the grocery store;
- Distilled water - at the hardware store.
Obtaining crystals from copper acetateFirst, prepare the solution of copper sulfate. We put glass on the bottom of the glass:
