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 it is not. Limestone itself is not a solution. Limestone is a rock which is primarily calcium carbonate as are marble and chalk. Calcium carbonate will react with water if the water contains dissolved Carbon Dioxide (forming a mild carbonic acid) resulting in Calcium Bicarbonate which is soluble and does form solution in water.
What happens when carbon dioxide gas is passed through calcium hydroxide solution?
When carbon dioxide gas is passed/bubbled through aqueous calcium hydroxide (also known as 'limewater'), a white precipitate will be formed. This means that the solution will turn cloudy/milky due to the formation of that white precipitate.Ca(OH)2(aq) + CO2(g) → CaCO3(s) + H2O(l)The precipitate, calcium carbonate, is only sparingly soluble in water. It will exist as a suspension in the resulting solution.But when excess carbon dioxide is added, this reaction takes place instead:CaCO3(s) + H2O(l) + CO2(g) → Ca(HCO3)2(aq)The calcium carbonate undergoes further reaction with water and carbon dioxide to form calcium bicarbonate (or calcium hydrogen carbonate), which is soluble. Thus the precipitate appears to 'disappear' or 'dissolve'. Thus, a colourless solution is formed.----- Other answers -----Water is added to give calcium hydroxide, and carbon dioxide is passed through this solution to precipitate the desired calcium carbonate, referred to in the industry as precipitated calcium carbonate (PCC):if carbon dioxide is passed through it it will turn cloudy and if it is done for to long then it will turn colourless.
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.
Calcium carbonate carbonic acid?
Well, well, well, look who's trying to test my chemistry knowledge. Calcium carbonate reacts with carbonic acid to form calcium bicarbonate, a compound that plays a role in buffering pH levels in the blood. So, there you have it, a little chemistry lesson served with a side of sass.

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 it is not. Limestone itself is not a solution. Limestone is a rock which is primarily calcium carbonate as are marble and chalk. Calcium carbonate will react with water if the water contains dissolved Carbon Dioxide (forming a mild carbonic acid) resulting in Calcium Bicarbonate which is soluble and does form solution in water.
Why ammonium oxalate is added in calcium carbonte solution?
ammonium oxalate is added to calcium carbonate because in the reaction between the two a crystal is formed that contain the Ca+2 ion. This is useful because if you have a sample of sodium carbonate with an unknown molarity you can use the oxalate to extract this calcium and determine what the molarity of the unknown solution was

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.
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.
