pKso for calcium carbonate is around 8.4, that means saturated solution is about 10-4 M (a little bit more, as solution of NH 4 + will be slightly acidic and carbonates will be protonated). Still, even if solubility will go up tenfold, that still means concentration of carbonates (which work as a base and neutralize NH 4 +) is about 1000 times bigger - so assumption that …
As the end product is calcium chloride and the gas formed is carbon dioxide, the metal compound A must be calcium carbonate. Therefore, the reaction between calcium carbonate and hydrochloric acid is ... Solution: Calcium hydroxide is the substance that on treatment with chlorine yields bleaching powder. Question 17 Name the sodium compound ...

Gallic acid, identified by Carl Wilhelm Scheele, is a grey powder with a sour taste that effervesces in calcium carbonate solution, is well soluble in ethanol and turns litmus red. Nowadays, it is commonly known that a pure GA is a colorless, crystalline powder.
As the LE of calcium carbonate is so large, a great amount of free energy would be required to break the strongly attracted ions apart, and this energy has to come from the enthalpy of hydration. In the case of calcium …
The initial total concentrations of calcium and total carbonate in supersaturated solutions are shown in Table 1. At t = 0, the solutions were seeded with 1 g of calcite of average size 2.17 /zm, measured with a Coulter LS particle size analyzer, and surface area of 0.997 m2/g, assuming a cubic shape for the particles.
