Limestone, or calcium carbonate, is insoluble in pure water. However, in an acidic aqueous solution (such as acid rain), calcium carbonate is appreciably more soluble. Therefore, a small amount of the material will be dissolved as it is washed by acid rain. Gradually, this can wear down things made of limestone, such as monuments or mountains.
how many protons does the carbonate ion have?
Acid rain is acidic. It has a low Ph. coaquina and other forms of limestone are alkaline. When the two combine there is a chemical reaction which will dissolve the limestone. The acid and the limestone will form a compound which is generically called a salt (probably calcium sulphate or calcium chloride). The amount of salt form will be dependent upon the acidity of the acid rain.
The formula mass of sodium carbonate, Na2CO3 is 2(23.0)+12+3(16) = 106.0 Amount of sodium carbonate = 2.12/106.0 = 0.0200mol
Calcium
No. Limestone is Calcium Carbonate. Limestone plus water makes wet calcium carbonate. With a very slight amount of calcium carbonate dissolving.

hydrochloric acid + calcium carbonate ▬▬► calcium chloride + carbon dioxide + water
Calcium carbonate is an alkali. It reacts with the acids and neutralises the acid rain.
Three different origins for limestone are Organic, Chemical and Bio-clastic Origins.
Generally dolomitic lime contains 25-30% CaCO3. The amount of any calcium in any lime is standardized to Calcium carbonate, using CCE, Calcium carbonate equivalent.
Limestone is crushed to a powder and heated in a furnace until the water of crystallisation is driven off. This is the water bonded within the calcium carbonate crystals. Once this is done it is called anhydrous(without water) calcium carbonate 'dry lime' or 'quicklime'. It is ground to a powder again and bagged.Upon mixing with water again an exothermic reaction occurs and produces a large amount of heat , enough to boil the added water.This is called slaked lime.
Experts state that calcium is best absorbed from the citrate malate form, or the type of calcium found in some juices, but they recommend calcium carbonate for the overall amount of calcium it offers and its affordability.
Well crustaceans make their shells from calcium carbonate, and when they die it puts extra calcium into the environment.
Calcium Carbonate is decomposed into Calcium Oxide and Carbon Dioxide when massive amount of heat is provided.
Limestone is made mostly of calcium carbonate and calcium sulfate. Limestone is eroded by water as the calcium carbonate and calcium sulfate of the stone disolves into running water. Also a factor: other things dissolved in the water. Carbon Dioxide disassociates in water becoming carbonic acid. This means that the more Carbon Dioxide in the water, the more acidic it is. The more acidic the water, the faster erosion can occur. When acidic ground water packed with lots of carbon dioxide is saturated with minerals - dissolved limestone - and that water enters an air filled chamber, the amount of mineral it can hold can suddenly change. This causes excess mineral to come out of solution as the water drips off the ceiling and onto the floor below into structures called Speleothem. .Think rock Icicle.
