A carbonate rock is known chemically as a carbonate salt. It has a metal cation ionically attracted to the carbonate anion. When a carbonate salt is placed in water, it will partially dissolve and some anions are formed. When acid is added, the carbonate reacts with the acid to form carbon dioxide and water. This means the anions that were in the water are no longer present. More of the salt dissolves in order to reach equilibrium and saturate the solution. However, the anions formed from that dissolution also react with the acid, and so forth until the entire rock (salt) is dissolved. The general reaction is as follows(where M is whatever metal is forming the rock with the carbonate):
MCO2(S) + 2H+(aq) --> M2+(aq) + H2O(l) + CO2(g)

How does rhyolite react to acid?
Rhyolite does not react with acid. Igneous rocks in general rarely react with acid.
Does limestone react to acid?
No. It is a sedimentary rock. However, unlike sandstone which is also a sedimentary rock, it is primarily composed of calcium carbonate which can be eaten away by acid (like acid rain) gradually with time.
How is carbon dioxide released into the air by carbonate rocks?
When acid rain reacts with the carbonate rocks, carbon dioxide is usually released into the air.
Caves and caverns are formed in carbonate rocks by?
The reaction of carbonic acid in rain and groundwater with the carbonate rock.
Does gneiss react with acid?
The metamorphic rock marble would react with hydrochloric acid.
Does Water and carbonic acid play a major role in the chemical weathering of rocks?
Yes, it is correct; for example calcium carbonate react with carbonic acid.
Is sodium carbonate soluble in hydrochloric acid?
Sodium carbonate react with hydrochloric acid !
What is the word equation for carbonate and acid?
Carbonate and acid react and produce, carbon dioxide and water as products.
Why does calcium carbonate react to acid rain?
sulfuric acid in the rain water reacts with calcium carbonate.
When Iron carbonate and formic acid react?
They react in aqueous solution.
What are the products when an acid and carbonate react together?
Acid Carbon reacting
How does Obsidian react to an acid?
Obsidian does not react with acid. Igneous rocks in general rarely react with acid.
How does rhyolite react to acid?
Rhyolite does not react with acid. Igneous rocks in general rarely react with acid.
How does granite react with acid?
Granite does not react with acid. Igneous rocks in general rarely react with acid.
What chemical reaction take place when acid rain damages buildings made of carbonate rocks?
The reaction that occurs when acid rain damages carbonate rocks is an acid-base reaction.
Do all rocks react with hydrochloric acid?
Basalt doesn't react with acid. Igneous rocks in general rarely react with acid.
How might a geologist use acid in the field to identify carbonate rocks such as anhydrite and gypsum?
If you put cold dilute Hydrochloric acid on a carbonate rock the acid dissolves the rock and you get bubbles of carbon dioxide in the acid. This reaction will only happen with carbonate rocks.
