10 Dilute hydrochloric acid reacts with calcium carbonate to produce carbon dioxide.(a) (i) With the aid of a diagram, design and describe an experiment in a laboratory to show how the rate of reaction between these two substances depends on the particle size of calcium carbonate.[4](ii)...
46. When powdered calcium carbonate reacts with dilute hydrochloric acid, the carbon dioxide gas is produced. If the complete reaction of calcium carbonate with dilute hydrochloric acid produces a maximum volume of 30cm3of carbon dioxide gas in 100 seconds, what is the average rate of this react...

calcium carbonate + hydrochloric acid → calcium chloride + water + carbon dioxide More generally An acid + a carbonate (or a hydrogen carbonate) → a salt + water + carbon dioxide To write it in symbols, it is important to ensure you have the correct formula for everything, and to then...
Other Characteristics: aragonite effervesces easily in cold dilute hydrochloric acid, is strongly birefringent, is fluorescent and its refractive index is 1.7 . Associated Minerals include gypsum, barite, smithsonite, malachite, calcite, serpentine, sulfur, celestite, zeolites, quartz, clays, dolomite,...
Calcium carbonate decomposes to calcium oxide and CO2 on heating. Treatment with dilute mineral acids produces corresponding calcium salts with liberation of CO2: CaCO3+ 2HCl →CaCl2+ H2O + CO2 In the presence of CO2 it dissolves in water with the formation of bicarbonate: ...

Here, we report the preparation of porous GPPCN using industrially available calcium carbonate particles as the hard template; these are not only low-cost, but also easily removed by dilute hydrochloric acid. Interestingly, upon engineering the w/w ratio of template to GPPCN precursor along with...
tated calcium carbonate, add 10 ml of dilute hydrochloric acid, shake throughly, and filter, if necessary. boil, then cool, and neutralize with ammonia ts: the solution responds to the qualitative tests < 1.09 > (1), (2) and (3) for calcium salt. (2)powdered precipitated calcium ...
