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 else can I help you with?
Does calcium carbonate dissolve in water?
Yes, calcium carbonate does dissolve in water to a limited extent.
If you add sugar to water and put a chalk inside will it dissolve?
No. Chalk is insoluble in water. Adding sugar will not change that.
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.
Is calcium carbon trioxide soluble in water?
No, calcium carbonate (CaCO3) is not soluble in water. It is considered sparingly soluble in water, meaning only a small amount will dissolve.
How would you separate water sodium carbonate and calcium carbonate?
To separate water, sodium carbonate, and calcium carbonate, you could first evaporate the water to leave behind the dry sodium carbonate and calcium carbonate. Next, you could use solubility differences to further separate the sodium carbonate and calcium carbonate; calcium carbonate is insoluble in water while sodium carbonate is soluble. So, you could dissolve the mixture in water, filter it to remove the calcium carbonate, and then evaporate the water to obtain the sodium carbonate.
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.
If you add sugar to water and put a chalk inside will it dissolve?
No. Chalk is insoluble in water. Adding sugar will not change that.

What are the properties of calcium carbonate?
insoluble in water
Is calcium carbon trioxide soluble in water?
No, calcium carbonate (CaCO3) is not soluble in water. It is considered sparingly soluble in water, meaning only a small amount will dissolve.
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.
How would you separate water sodium carbonate and calcium carbonate?
To separate water, sodium carbonate, and calcium carbonate, you could first evaporate the water to leave behind the dry sodium carbonate and calcium carbonate. Next, you could use solubility differences to further separate the sodium carbonate and calcium carbonate; calcium carbonate is insoluble in water while sodium carbonate is soluble. So, you could dissolve the mixture in water, filter it to remove the calcium carbonate, and then evaporate the water to obtain the sodium carbonate.
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.
