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.
No one will ever answer you because there is no question.
Ethanoic acid = H3COOH
Calcium Carbonate (chalk) = CaCO3
COOH is -3
CO3 is -2
You will probably need to explain this better to get an answer.
it contains base
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.
Carbonic acid dissolves limestone by turning the mostly insoluble calcium carbonate into soluble calcium bicarbonate. The dissolution hollows out areas the the rock, creating caves. When one of these caves collapses a sinkhole will form above.
The calcium carbonate reacts with the acid as per any carbonate: Calcium Carbonate + Acid -> Calcium Salt + Water + Carbon Dioxide
Errrrr..... and the question is? Carbonic acid is a solution of carbon-dioxide in water. It can dissolve limestone (calcium carbonate), dolomite (magnesium carbonate) and gypsum (calciumm sulphate). +++ This was flagged on "gibberish" grounds. The question is badly worded but but after gently teasing the writer about that, I answered seriously & concisely what I took to be his or her enquiry.
No it is not. Limestone itself is not a solution. Limestone is a rock which is primarily calcium carbonate as are marble and chalk. Calcium carbonate will react with water if the water contains dissolved Carbon Dioxide (forming a mild carbonic acid) resulting in Calcium Bicarbonate which is soluble and does form solution in water.
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.
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.
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.
Yes, it is correct; for example calcium carbonate react with carbonic acid.
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
Carbonic acid and Calcium chloride are produced in the reaction between calcium carbonate and hyrdochloric acid. CaCO3 + 2HCl --> H2CO3 + CaCl2
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
carbonic acid
Carbonic Acid/Hydrogen Carbonate
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.
Calcite, which is the compound calcium carbonate (CaCO3) forms carbonic acid (H2CO3) which decomposes into water and carbon dioxide gas.
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.
