What happens when calcium carbonate reacts with rainwater?
When calcium carbonate reacts with rainwater, it forms a weak acid called carbonic acid. This reaction can lead to the erosion of limestone or marble surfaces over time. Additionally, it contributes to the process of chemical weathering in nature.
Can chalk dissolve in HCl and why?
No, chalk (calcium carbonate) does not dissolve in hydrochloric acid (HCl) because calcium carbonate is insoluble in acids. When HCl is added to chalk, it will react with the calcium carbonate to form calcium chloride, water, and carbon dioxide gas, but the chalk itself will not dissolve.
Why does Calcium carbonate dissolve in rain water - when it is insoluble in pure water?
Rain water is not pure H2O. Even under natural conditions, rain water can contain carbonic acid (due to CO2), and lightning can cause the creation of nitric acid. So these acids can attack calcium carbonate even in unpolluted rainwater.Additionally, the rainwater might be polluted with even stronger acidic compounds. Sulfuric acid, for example, is a common pollutant of rain water.
What happens when H2O is added to CaCO3?
When H2O is added to CaCO3 (calcium carbonate), it can cause a chemical reaction where calcium carbonate may dissolve to form calcium ions (Ca2+) and carbonate ions (CO3 2-). This can result in the formation of a solution containing calcium ions and carbonate ions.
Will calcium carbonate be dissolve in sodium chloride?
No, calcium carbonate is not soluble in sodium chloride. When calcium carbonate is mixed with sodium chloride in water, the calcium carbonate will remain as solid particles and not dissolve into the solution.
Calcium carbonate is insoluble in pure water why does it dissolve in rain water?
Because rainwater, with the different chemicals and elements in it, is very slightly acidic.
Will powdered chalk dissolve?
Calcium carbonate is insoluble in water.
Is there any base that does not dissolve in water?
Yes, there are many insoluble bases such as calcium carbonate.

Does calcium carbonate dissolve in water?
Yes, calcium carbonate does dissolve in water to a limited extent.
Why isn't calcium carbonate insolube in water?
Calcium carbonate is almost insoluble in water.
What is the product when calcium carbonate is added to water?
When calcium carbonate is added to water, it will form a suspension where the calcium carbonate particles are dispersed in the water. While some of the calcium carbonate may dissolve into calcium ions and carbonate ions, the majority will remain as solid particles in the water.
Why would you choose calcium chloride for the reagent to precipitate the soluble carbonate?
Calcium chloride is chosen as a reagent to precipitate soluble carbonates because it forms insoluble calcium carbonate when reacted with a carbonate compound. The insoluble calcium carbonate precipitates out of the solution, allowing for the separation of the carbonate from the remaining solution.
