Zinc-making agent says
If you want to make "Zinc Acetate Dihydrate Sigma", you must study the method in detail. First, you need to prepare all kinds of utensils, clean and fine, to avoid the disturbance of impurities.

As for the material used, you should seek purity. For zinc, it is better to be pure, its color is silver and white, and its sex is firm and soft. For acetic acid, you must also choose the best one, which has a sour taste and no impurities. For water, use a clear spring, or water that has been carefully filtered, to avoid dust.

When preparing, use a moderate utensil to contain zinc, slowly inject acetic acid into it, and at first the reaction will be peaceful, and gradually the gas will surge. In the meantime, it must be heated with a slight fire, but it should not be too intense, for fear of losing its properties. After the reaction is exhausted, the liquid gradually clarifies, and then the residue is removed with a fine filter.

Then, take the obtained clear liquid and place it in an open container in a ventilated and cool place, waiting for the moisture to gradually evaporate. As the sun shifts, the liquid gradually thickens and eventually crystals emerge, which is the initial form of "Zinc Acetate Dihydrate Sigma".

Repeat this crystal with pure water, and then dry it over a small fire several times until it is dry and pure in color. "Zinc Acetate Dihydrate Sigma" is formed. The way of making is to care about being careful and steady, to observe its change in the slightest, and to control its warmth in moderation, in order to obtain good things.
