This paper focused on the analysis of the crystal structure and phase transformation of CaCO 3 synthesized by simple solution method from 0.5 M Ca(NO 3) 2 precursor and 0.5 M Na 2 CO 3 precipitant at ambient temperature (300 K). The pH of the sample solution at various reaction times of 5, 10, 15, and 30 min were measured and …

If the water in a well has 1000.0 mg/L of CaCO3 dissolved in it, how many grams of Na2C2O4 could you mix with 100.0 mL of that water before a precipitate would form? How many grams of CaCO3 will dissolve in 2.70 x 10^2 mL of 0.0460 M Ca(NO3)2? The Ksp for CaCO3 is 8.70 x 10^9. How many grams of CaCO3 will dissolve in 3.00x10^2 mL of …

I would convert the 1 kg of CaCO3 into grams and then moles. (1kg CaCO3) x (1000g/1kg) x (1mol/100.0869g -- molar mass of CaCO3) = 9.99131 which is about 10 mol CaCO3. Based on the molar ratio in the balanced equation, 1 mole of CaCO3 = 1 mole of CO2. Therefore, 10 moles of CO2 will be produced from 1 kg of CaCO3. Hope this helps!

Calcium carbonate (CaCO3) is a substance widely used for various purposes, for example, as a filler and pigment material not only in paper, plastics, rubbers, paints, and inks but also in pharmaceutics, cosmetics, construction materials, and asphalts and as a nutritional supplement in animal foods (1).

Calcium carbonate is not soluble in water as the lattice energy of the compound is very high in comparison to its hydration energy. Also, the solubility product for the CaCO3 compound is very low 3.3 X 10-9 indicating that this compound cannot dissolve in water. Mostly solubility increases with an increase in temperature but in the case of ...
