The Food and Drug Administration classifies calcium sulfate as GRAS - generally recognized as safe. Their opinion is shared by the European Food Safety Authority, who assessed calcium sulfate as safe in 2008. Exceeding your daily limit for calcium - about 2,500 milligrams in healthy adults - can make you constipated.
Note that solubility of sulfides depends on pH. If it's not on the solubility list of "common" anions and doesn't have an alkali metal counterion (since alkali metal salts are generally soluble), you can pretty safely assume it's not soluble. CaS reacts with water to form mixed calcium hydroxide/hydrosulfide.
calcium-sulfide replied to lostpasswordagainnn. I had such bad reactions to vaccines (not just covid—HPV and flu, too) while I was living in mold that I am terrified of getting vaccinated for anything ever again. It basically ruined my life. That, and (medically necessary) antibiotic use during mold exposure.
Calcium(I) disulfide doesn’t exist but it would have the formula [Ca⁺]₂[S₂²⁻] or Ca₂S₂ which is what I was talking about. Calcium disulfide aka calcium (II) disulfide does have the formula CaS₂ however
Calcium sulfide help guys, what's the difference between Ca2S2 and CaS, because when I search with both, it gives me the same name and websites? If they are the same, where did the number "2" go?
Unit: Chemical Reactions. “Predicting Products - SR” – WS #5. Directions: Predict the products for each of the following reactions in words. calcium + magnesium sulfide →. sodium + silver chloride →. iron (II) sulfide + potassium →. barium + aluminum nitrate →. potassium iodide + chlorine →. zinc + lead (IV) chloride →.
BlackPhoenixSoftware. ADMIN MOD. Neutralizing Hydrogen Sulfide with Calcium Nitrate. Hi guys, i have a fish tank (its actually a crab tank) with a 1 to 1 1/2 inch layer of sand. The water was pretty still and the anoxic layer developed too fast and the bacteria there are producing poisonous hydrogen sulfide. I will be adding air stones near the ...
The test samples have calcium sulfide mixed at a 1 to 10 ratio CS/H2O. This has been going for about 2 months now. The colors are absolutely amazingly vivid but it doesn’t seem to be killing. Every test colonized from the top down and have performed very similar. Here are pictures of some of the test samples.
Calcium Carbonate+Carbon+Sodium Sulfate = Sodium Carbonate. Sodium Carbonate+Ammonia+Wolframite=APT. APT+Heat = Tungsten Oxide. Tungsten Oxide+Hydrogen+Heat = Tungsten. Tungsten+Steel=High Speed Steel (Used for dies, tools, etc) There is more then one way to make sodium carbonate in the game but that is the beginning recipe. Add a Comment.
