As mentioned, most calcium tablets can safely be cut/or split. There is nothing inherent about calcium where crushing it would reduce its effectiveness or absorption. Tums, for example, the popular antacid, is a chewable form of calcium carbonate.
Question: The reaction of calcium carbonate with sulfuric acid yields carbon dioxide, water, and calcium sulfate. Write a balanced chemical equation for the reaction of sulfuric acid with calcium carbonate
Ya I feel you. I'm in the process of unlearning a few of the things that you had mentioned, like putting directly into water after cutting. It seems like common practices are far from best practices. what I'm currently doing because it works for me is rockwool on a bed of vermiculite soaked in light nutes phd. Closed domes vents for a few days then open.

Balanced chemical equation of CaCO 3 and HCl reaction with physical states CaCO 3(s) + 2HCl (aq) → CaCl 2(aq) + CO 2(g) + H 2 O (l). Calcium carbonate is not soluble in water and exists as white precipitate in the water. When aqueous hydrochloric acid is added, you can observe air bubbles are generated and calcium chloride, carbon dioxide and water are formed.

Whiting- Calcium Carbonate – CaCO 3 (m.p. 4650 o F/2570 o C) is a finely ground powder composed essentially of pure Calcium Carbonate derived from Limestone, Chalk, or Marble. It is the most common source of Calcium in a glaze and clay body. In stoneware glazes (cone 7-12), it promotes a matt finish and produces a harder and more chemically resistant glaze.
