No, calcium carbonate (CaCO3) is the calcium salt of carbonic acid (H2CO3). If a compound has the name of a metal in it (sodium, calcium, copper, etc) it is generally not an acid but a salt. A salt is formed when a metal ion or other positive ion takes the place of hydrogen in an acid.

Is calcium carbonate a buffer?
Yes. Calcium carbonate is a salt and is formed from calcium reacting with carbonic acid. The salts of weak acids function as buffers. Carbonic acid is a weak acid.
What is calcium cabonate plus hydrochloric acid?
Carbonic acid and Calcium chloride are produced in the reaction between calcium carbonate and hyrdochloric acid. CaCO3 + 2HCl --> H2CO3 + CaCl2
Why does calcium carbonate powder fizz when in acid?
When calcium carbonate, or any carbonate is placed in acid, the carbonate ion (CO3^2-) accepts protons from the acid, forming carbonic acid (H2CO3), which is unstable and spontaneous breaks down into carbon dioxide gas (the cause of the bubbles) and water. H2CO3 --> CO2 + H2O
What acid reacts with carbonate?
carbonic acid
Why does calcite fizz in acid?
Calcite, which is the compound calcium carbonate (CaCO3) forms carbonic acid (H2CO3) which decomposes into water and carbon dioxide gas.
Is calcium carbonate a buffer?
Yes. Calcium carbonate is a salt and is formed from calcium reacting with carbonic acid. The salts of weak acids function as buffers. Carbonic acid is a weak acid.
Which type of acid has calcium carbonate?
No acid contains calcium carbonate. Calcium carbonate is its own compound that is a base, not an acid. However, the erosion and deposition of calcium carbonate in nature is heavily influenced by carbonic acid.
Calcium carbonate carbonic acid?
Calcium carbonate (CaCO3) and carbonic acid (H2CO3). The two hydrogen in cabonic acid are attached to oxygen and hence are acidic (they can be removed as protons). This gives carbonic acid its acidity.
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.
What is calcium cabonate plus hydrochloric acid?
Carbonic acid and Calcium chloride are produced in the reaction between calcium carbonate and hyrdochloric acid. CaCO3 + 2HCl --> H2CO3 + CaCl2
How does carbonation chemically weather rocks?
Ø Carbonation occurs on rocks which contain calcium carbonate such as limestone and chalk. Ø Carbon dioxide dissolved in rainwater forms weaker carbonic acid that reacts with insoluble calcium carbonate, changing it into soluble bicarbonate. This takes place when rain combines with carbon dioxide or an organic acid to form a weak carbonic acid which reacts with calcium carbonate (the limestone) and forms calcium bicarbonate. Ø The reactions as follows: Ø CO2 + H2O => H2CO3 Ø Carbon dioxide + water => carbonic acid Ø H2CO3 + CaCO3 => Ca (HCO3)2 Ø Carbonic acid + calcium carbonate => calcium bicarbonate

What acid reacts with carbonate?
carbonic acid
What is the IUPAC nomenclature of h2co3?
Carbonic Acid/Hydrogen Carbonate
Why is carbon dioxide produced when a carbonate react with acids?
Carbonates contain the carbonate ion CO32-. Acids release hydrogen ions, H+. In the presence of an an acid, the carbonate ion will form carbonic acid, H2CO3, an unstable molecule that readily breaks down into water and carbon dioxide.
Why does calcite fizz in acid?
Calcite, which is the compound calcium carbonate (CaCO3) forms carbonic acid (H2CO3) which decomposes into water and carbon dioxide gas.
How does the formation of stalactite related to the action of acids on calcium carbonate?
The acid is Carbonic Acid, formed by Carbon Dioxide from the atmosphere dissolving into rain-water, and though very weak capable of dissolving limestone whose main constituent is calcium Carbonate. The stalactites are of calcite, crystallised calcium carbonate precipitated from that solution.
