First determine what the products are. You should find that one of the products is a gas. So, you can monitor this gas and see when it is stopped being produced (watch for bubbles).
calcium carbonate + Hydrochloric acid= Calcium chloride + water + carbon dioxide
The reaction between limestone and hydrochloric acid is an acid-carbonate reaction producing a salt, carbon dioxide and water. Limestone is chemically known as calcium carbonate (insoluble salt) and has the formula CaCO3. Hydrochloric acid is an acid and is written as HCl. When calcium carbonate and hydrochloric acid reacts the following is formed: - Calcium chloride CaCl2 (soluble salt) - Carbon dioxide (CO2 gas) - Water (H2O) Due to the carbon dioxide being released, the observer will be able to see bubbling, effervescence or fizzing. CaCO3(s) + 2H+(aq) + [2Cl-(aq)] --> Ca2+(aq) + CO2(g) + H2O(l) + [2Cl-(aq)]
have any reaction between calcium carbonate & milk
CO2 gas is formed, and as it is leaving the instrument in which this reaction is done in, the mass decreases.
Heating of calcium carbonate (and the transformation in calcium oxide and carbon dioxide) is not a synthesis; it is a reaction of thermal dissociation.
calcium chloride
The chemical reaction goes faster if calcium carbonate is powdered.
The reaction is:CaCO3 + 2 HCl = CaCl2 + CO2(gas) + H2OThe reaction is finished when CaCO3 is integrally reacted.
The gas released in the reaction of calcium carbonate with hydrochloric acid is carbon dioxide. CaCO3 + 2 HCl = CaCl2 + CO2 + H2O
lots of fizzing because of the CO2
Because chemically, both are mainly made from calcium carbonate.
Hydrochloric acid reacts with calcium carbonate to produce calcium chloride, carbon dioxide and water. The balanced reaction is shown below: CaCO3 + 2HCl --> CaCl2 + CO2 + H2O This reaction is effervescent since CO2 bubbles will be seen. Also it is an example of a neutralization reaction in which hydrochloric acid is a strong acid and calcium chloride is weak base.
calcium carbonate + Hydrochloric acid= Calcium chloride + water + carbon dioxide
CaCO3 + 2HCl => CaCl2 + CO2 + H2O
CaCO3 + 2HCl --> CaCl2 + CO2 + H2O

The total amount of carbon dioxide gas will stay the same if the reaction goes to completion, but if you crush the calcium carbonate, it would make the reaction occur more rapidly, because more surface area would be exposed to the hydrochloric acid.
