Making calcium acetate from eggshells

welcome back everyone today we are going to make calcium acetate for this you will need 107 grams of egg shells 200 milliliters of 60 acetic acid and some distilled water eggshells are mostly made of calcium carbonate and therefore they will react with acetic acid to form calcium acetate we first crush all the eggshells down into the beaker maximize the surface area and speed up the reaction to the eggshells just a little distilled water was added to cover them all up because our acetic acid is a little too concentrated afterwards approximately 200 ml of 60 acetic acid were measured out these were done simply added to the egg shells you can see that immediately a reaction starts this is because the calcium carbonate in the egg shells reacts with the acetic acid to form calcium acetate water and carbon dioxide which you can see here the beaker was left to stand until everything had dissolved and this might take a while at least two hours to prevent the beaker from overflowing i occasionally use the blowtorch to keep the foam down this actually works really well and because we gotten large excess of acetic acid the small amount that evaporated and from the acetone didn't matter four days later it looked like nothing was happening anymore for this reason a simple filtration gravity filtration setup was set up and all of this stuff was poured into the filter the goal here is to get rid of all of this organic gunk contained in our acetic acid and calcium acetate solution afterwards we were left with this dirty looking liquid which has to be boiled down carefully if it gets too hot while boiling it down it will decompose into acetone some acetate distilled water acetic acid solution will stain boil down carefully using a hot plate after a while you were able to see some white flocks of calcium acetate starting to precipitate after boiling off most of the water we were left with this we didn't heat it up till it was completely dry because we don't want it to decompose the acetone now we are going to transfer it to this plastic tray to dry completely it was then spread out nicely to increase its surface area and to speed up the drying process after only a few days we were left with this bone dry calcium acetate powder calcium acetate is definitely not pure and therefore we are only going to put it into a plastic bag and not into a fancy container so while filling this bag i did not wet any gloves because calcium acetate isn't dangerous in total we collected 98 grams of calcium acetate and what can you use this stuff for well you can use it to make acetone you could make alcohol jelly but we are going to make acetophenone from calcium acetate and calcium bandwidth because this topic hasn't been covered that much on youtube before so if you like this video make sure to drop me one of these and consider subscribing to my channel for more chemistry content in the future i wish all of you a nice day until next time bye
