This work deals with the preparation of calcium chloride whiskers by reactive crystallization process with sulfuric acid and calcium chloride discharged from Solvay process. Firstly, the orthogonal experiments were carried out using both CaCl2 and H2SO4 in analytic grade as feedstock, and the reactive...
Another importantcompoundiscalcium chloride, CaCl2, a colourless or white solid produced in large quantities either as a by-product of the manufacture ofsodiumcarbonate by theSolvay processor by the action ofhydrochloric acidon calcium carbonate. The anhydrous solid is used as a drying agent and fo...

Dibasic calcium phosphate is produced by the reaction of phosphoric acid, calcium chloride, and sodium hydroxide. Calcium carbonate can be used in place of the calcium chloride and sodium hydroxide. Dibasic calcium phosphate anhydrous is generally regarded as relatively nontoxic and nonirritant material...
Calcium sulfate,CaS04, is a grayish-white dense powder that occurs in nature in both an anhydrous form (anhydrite) and hydrated form(gypsum); it is also the byproduct of many chemical reactions. It has many industrial uses;for example, as a source of sulfur and sulfuric acid,in cements,...
Calcium chloride is the form in which calcium gets absorbed by the body since it contains 27% of elemental calcium and is freely soluble in water. Calcium carbonate reacts with the gastric HCl present in the stomach and dissociates to calcium chloride and bicarbonate. However, calcium chloride ...
mL of 2.7 N hydrochloric acid and 16 mL of water. A white precipitate forms when 5 mL of ammonium oxalate TS is added to 10 mL of the solution. Upon the addition of barium chloride TS to the remaining 10 mL, a white precipitate forms that is insoluble in hydrochloric and nitric acids...
Sodium sulfate is added into by-product (calcium chloride) of ammonia and alkali method to product alkali, the reaction product is refined to get calcium sulfate dihydrate. Byproduct of manufacturing organic acid. For example: The byproduct calcium oxalate is decomposed by sulfuric acid when oxalic...
Conditions: Store in a cool and dry place. View all 3.2 Usage CALCIUM SULFIDE is used in electron emitters. Luminous CaS used for making luminous paints or varnishes.4. Safety and Handling4.1 Safety A poison via inhalation. Reacts violently with chromyl chloride, lead dioxide, potassium chlor...
In a similar reaction, sulfuric acid reacts with calcium formate to provide low-cost solutions of formic acid: Ca(OOCH)2 + H2 SO4 → CaSO4 + 2HCOOH When heated, calcium formate decomposes to calcium carbonate and formaldehyde: Ca(OOCH)2 → CaCO3 + HCHO ...
