CaCl

The question is whether calcium chloride sold in pharmacies for injections can be converted to dry form and then diluted to the desired percentage, or where to buy about a kilogram of dry calcium chloride, but not for 350 grams; the real price is 11 grams per kilogram, but it is sold in bags, and 1 kg would be enough for a year.

If you are satisfied with the price, then here: 17. Calcium chloride food grade (CaCl2), food – 10 /100g;

CaCl2 11 grams per kilogram, we have workers in the port who scoop it with a shovel, and with the same shovel - fertilizers, pesticides for the fields... If you want to fertilize your garden - take it, it won't be bad.

In SPS, a more reasonable price. It's not a fact that imported ones are handled with kid gloves; the only difference in price is that if there's a cheaper option, why buy the more expensive one?

There is another problem here, the heat is high, the humidity is high, and it seems that the salt has absorbed that moisture and doesn't want to dissolve completely. Something has settled at the bottom and it hasn't dissolved for 2 days - is this very critical? If I pour it into the aquarium with the sediment, or carefully drain the top and fill the bottom with osmosis water and try to dissolve it again? Or should I just throw it away and buy new salt?

It's better not to. It's the right decision.

Overpayment goes for the purity of the product!

Actually, the question is about calcium chloride. I have always bought pharmaceutical grade hexahydrate calcium chloride, priced around 75 per kg. But now it is not available for sale. There is food-grade calcium chloride (as mentioned above), priced around 15 per kg. Can food-grade calcium chloride be used?

Heather2018

so, I used it.

Mike

And what conclusions can be drawn? One more question, what is the difference between pharmacopoeial and food grade? I understand that it might be in purity, but could someone explain in more detail?

Chad

Only laboratory studies can provide this; everything we do is conduct experiments without a scientific basis. Both can be used, but the proportions are different in the mixtures. There is a lot of information on forums.

I used both food-grade and technical-grade for analysis. I did not notice any differences. The technical-grade (according to the certificate) has 3% impurities. The food-grade, according to GOST, has up to 4%.

Tracy

There are no different proportions; both CaCl2 are the same, the difference is in the post above. I bought calcium and was not satisfied; they sent me technical instead of food-grade. Moreover, it was wet and in chunks that were hard to break. When I dissolved it, I saw a reddish precipitate and threw it away. I contacted them before that, and they said it was fine, just wet. I buy from the same supplier, and theirs is not only packaged but also sealed.

Are you serious???

CaCl2 + 2H2O, whether food grade or technical, is one proportion, while for anhydrous CaCl2 it is another. They differ in formula, but not in the degree of purity (food grade, technical, etc.).

Be more careful...

Elizabeth1221

There is food-grade calcium chloride with the formula (CaCl2 + 2 H2O), and they differ in the degree of purification from (CaCl2 + 2 H2O) technical, so the proportion is the same. If you have anhydrous CaCl2, then the proportion is different. If (CaCl2 + 6 H2O), then it is a completely different proportion as indicated by Nickanya in the previous post in the calculator.
