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.
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.
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.

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! :)
What happened when soluble carbonate is passed through soluble calcium salt?
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)
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.
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.
Calcium carbonates be used to remove acidic gases from power stations?
Yes, calcium carbonate can be used to remove acidic gases like sulfur dioxide and nitrogen oxides from power station emissions through a process called flue gas desulfurization. This involves the reaction of calcium carbonate with the acidic gases to form less harmful products like calcium sulfate and water.

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.
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.
When carbon iv oxide is bubbled through calcium hydroxide what is the white precipitate formed?
The precipitate formed is Calcium Carbonate (CaCO3).
How do you test for carbon dioxide when calcium carbonate reacts with acid?
To test for carbon dioxide gas produced when calcium carbonate reacts with acid, you can bubble the gas through limewater. If carbon dioxide is present, it will turn the limewater cloudy or milky due to the formation of calcium carbonate.
