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 pure carbon dioxide in the presence of a dithionite bleaching reagent to form a precipitate of an alkaline earth metal carbonate of increased brightness and purity. The precipitate may then be separated from the aqueous medium by, for example, filtration.

What is the word equation for the reaction between acid and metal carbonate?

The word equation for the reaction between acid and metal carbonate is acid + metal carbonate → salt + water + carbon dioxide.


What is the word equation between acid and metal carbonate?

metal carbonate + acid = metal salt + carbon dioxide + water e.g. calcium carbonate + hydrochloric acid = calcium chloride + water + carbon dioxide CaCO3 + 2HCl = CaCl2 + H2O +CO2


What is a metal carbonate that soluble in water?

Sodium carbonate (Na2CO3) is a metal carbonate that is soluble in water. It forms a basic solution upon dissolving in water.


How do you prove that given salt is carbonate of a metal?

To prove that a salt is a carbonate of a metal, you can add an acid to the salt. If carbon dioxide gas is produced, it indicates the presence of a carbonate. This can be further confirmed by testing the gas with limewater; if it turns milky, it confirms the presence of carbon dioxide, which suggests the salt is a carbonate of a metal.


What is produce when a metal carbonate reacts with an acid?

When a metal carbonate reacts with an acid, the products are a salt, carbon dioxide gas, and water. The salt formed will depend on the specific metal in the carbonate and the acid used in the reaction.


If the carbonate of a metal contains 50 percent metal then what will be the equivalent mass of metal atom?

Taking carbonate (CO3^2-) as 60 g/mole, the equivalent mass of metal would be 60/2 = 30 since carbonate is 2- anion


What is copper carbonate plus potassium?

When copper carbonate reacts with potassium, it forms copper metal and potassium carbonate. This reaction is a redox reaction where copper is reduced and potassium is oxidized.


When Heated a metal carbonate produces what?

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
