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 else can I help you with?
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.
What is the formula for a carbonate?
MeCO3 where Me is a metal.
What are the three common metal carbonates?
Sodium Carbonate Potassium carbonate Lithium carbonate Magnesium carbonate
Is calcite a metal?
No. Calcite is a carbonate mineral.
Is sodium hydrogen carbonate is metal carbonate?
no
Name a metal carbonate that does not decompose?
Magnesium carbonate is a metal carbonate that does not decompose easily at room temperature or below.
Is calcium carbonate a metal?
No, it is not. Calcium is a metal but calcium carbonate is not.
What is the metal in calcium carbonate?
Calcium is a metal
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
