A white precipitate of calcium carbonate forms. This reaction occurs because carbonate ions (CO3^2-) from the soluble carbonate solution react with calcium ions (Ca^2+) from the soluble calcium salt to form insoluble calcium carbonate. The balanced chemical equation for this reaction is: Ca^2+ + CO3^2- -> CaCO3(s)

How do you separate sodium chloride from calcium carbonate?
Dissolve the sodium chloride(which is actually salt) in water. Then, filter the calcium carbonate with the help of filter paper. Crystallize the solution of sodium chloride with water... Hope this helps! :)
Is limestone a solution?
No, limestone is a sedimentary rock primarily composed of the mineral calcite. It is not a solution, but rather a solid mineral that forms through the accumulation of calcium carbonate deposits over time.
What happens when carbon dioxide gas is passed through calcium hydroxide solution?
When carbon dioxide gas is passed through calcium hydroxide solution, calcium carbonate is formed as a white precipitate. This reaction is a classic example of a neutralization reaction, where carbon dioxide reacts with calcium hydroxide to form calcium carbonate and water. The equation for this reaction is: CO2 + Ca(OH)2 → CaCO3 + H2O
What chemical limestone form?
Limestone is primarily composed of the mineral calcite, which is a crystalline form of calcium carbonate (CaCO3). This chemical forms through the precipitation of calcium-containing ions in water, or can be produced by the accumulation of marine organisms such as corals and mollusks over time.
What does Calcium Carbonate produce after going through a decomposition reaction?
Calcium Carbonate undergoes a decomposition reaction when heated, producing Calcium Oxide (quicklime) and Carbon Dioxide gas.
How do you separate sodium chloride from calcium carbonate?

How calcium carbonate can be removed from the mixture?
Calcium carbonate can be removed from a mixture by using a process called filtration or decantation. In filtration, the mixture is passed through a filter paper, which allows the liquid to pass through while retaining the solid calcium carbonate. In decantation, the mixture is left undisturbed to allow the solid calcium carbonate to settle at the bottom, and the liquid can then be carefully poured off.
How calcium carbonate solve in water?
Calcium carbonate dissolves in water through a process called dissociation. When calcium carbonate is added to water, it breaks down into calcium ions (Ca^2+) and carbonate ions (CO3^2-). These ions then interact with water molecules, causing the calcium carbonate to dissolve.
Is limestone a solution?
No, limestone is a sedimentary rock primarily composed of the mineral calcite. It is not a solution, but rather a solid mineral that forms through the accumulation of calcium carbonate deposits over time.
Why ammonium oxalate is added in calcium carbonte solution?
Ammonium oxalate is added to a solution of calcium carbonate to precipitate calcium oxalate, which can then be used as a method to determine the amount of calcium present in the solution through gravimetric analysis. The reaction between calcium carbonate and ammonium oxalate forms a sparingly soluble calcium oxalate precipitate, which can be filtered out and weighed to calculate the calcium concentration in the original solution.
What happens when carbon dioxide gas is passed through calcium hydroxide solution?
When carbon dioxide gas is passed through calcium hydroxide solution, calcium carbonate is formed as a white precipitate. This reaction is a classic example of a neutralization reaction, where carbon dioxide reacts with calcium hydroxide to form calcium carbonate and water. The equation for this reaction is: CO2 + Ca(OH)2 → CaCO3 + H2O

How does calcium carbonate become limestone?
Calcium carbonate is deposited from marine or freshwater sources over time, accumulating in layers and eventually forming limestone through compaction and cementation processes. The accumulation of shells, coral, and other biological remains containing calcium carbonate contribute to the formation of limestone.
From where does the calcium carbonate that makes a speleothem come?
Calcium carbonate in speleothems comes from the dissolution of limestone or dolomite bedrock by slightly acidic groundwater. This dissolved calcium carbonate is then deposited in caves as stalactites, stalagmites, and other formations through the process of precipitation.
What happens when excess of CO2 is passed through lime vessel?
When excess CO2 is passed through a lime vessel, it reacts with the lime (CaO) to form calcium carbonate (CaCO3) through a process called carbonation. This reaction removes the excess CO2 from the system and produces calcium carbonate as a white precipitate.
Is the decomposition of calcium carbonate reversible or irreversible?
The decomposition of calcium carbonate is reversible as it can be reversed by recombining calcium oxide and carbon dioxide to form calcium carbonate again through a chemical process known as carbonation.
How crystals of calcium chloride made from calcium carbonate and dilute hydrochloric acid?
Crystals of calcium chloride can be made from calcium carbonate and dilute hydrochloric acid through a chemical reaction where calcium carbonate reacts with hydrochloric acid to form calcium chloride, carbon dioxide gas, and water. The resulting solution can be further evaporated to allow crystals of calcium chloride to form.
