Limestone is calcium carbonate. If you have a spill of calcium carbonate on the surface try brushing or polishing the floor.
Limestone is made of Calcium Carbonate and is therefore a source of atmospheric Carbon dioxide when it weathers. CaCO3 -> CaO + CO2
Limestone, aka calcium carbonate (CaCO3) reacts with acid to forma calcium salt, water and carbon dioxide. This is how it can remove acid in soil. CaCO3 (s) + 2H+ (aq) --> Ca2+ (aq) + H2O (l) + CO2 (g)
The lime (CaO) reacts with SO2: 2CaO (s) + 2SO2 (g) + O2(g) .........> 2 CaSO4 (s) So the sulphur dioxide is removed and deposited as calcium sulphate.
Limestone is a substance composed mainly of calcium carbonate. It's not a mixture but a compound formed naturally. Delve deeper into its properties and formation in my free course.

Basically, sulfur dioxide is a acidic gas. As acid reacts with alkali, carbonates and metals, all 3 are actually ideal to remove sulfur dioxide. However, in the context of removing sulfur dioxide due to air pollution, reacting sulfur dioxide with alkali and carbonate would be more appropriate. For example, removing sulfur dioxide with calcium carbonate would result in calcium sulfate, water and carbon dioxide.

no.
1. Removing of calcium carbonate: CaCO3 is dissolved in vinegar. 2. Obtaining of pure calcium carbonate: by heating of birds eggshells at moderate temperature, to destroy the proteic matrix.
It will make the water cloudy. to remove calcium carbonate simply lower pH in the pool to 7.0 or lower and calcium carbonate will redissolve back into suspension and water will clear up. You can get this characteristic by adding sodium Carbonate too quickly.
Calcium carbonate easily react with acids and a neutralizing reaction occur.
Acid, to help remove calcium carbonate and rust deposits.
Precipitation is used to remove unwanted ions most commonly in water softeners. Sodium carbonate is added to the water to precipitate calcium carbonate.

Muratic Acid
most toothpastes contain an abrasive such as calcium carbonate to help remove the plaque
These substances are acids.
Most water softeners remove calcium and limestone. These are not really harmful to humans, but cause a scaly build up in pipes and tanks.
