How could you prove that CO2 is produced when a metal carbonate is heated?
Experimentally to prove that, capture the gas and pass it through lime water.
If the lime water turns milky then the gas is CO2 .
Or an example of equation for decomposition of a metal carbonate is :-
MgCO3 + heat ------> MgO + CO2
A precipitated alkaline earth metal carbonate is produced by calcining raw alkaline earth metal carbonate, for example a calcium carbonate, under conditions such that substantially all the chemically combined carbon dioxide is driven off to form an oxide, slaking the oxide in water to form a suspension of the corresponding alkaline earth metal hydroxide, allowing the suspension to cool to 45° C. or below, and then carbonating the hydroxide in suspension in water with substantially…
If the carbonate of a metal contains 50 percent metal then what will be the equivalent mass of metal atom?
Generally, when an acid reacts with a metal carbonate, the products, the reaction products are: water, carbon dioxide, and a salt specific to the metal and the acid, e.g: hydrochloric acid + sodium carbonate → sodium chloride + carbon dioxide + water. 2HCl + Na2CO3 → 2NaCl + CO2 + H2O Generally, when an acid reacts with a metal hydroxide, the products, the reaction products are: water, and a salt specific to the metal and…
