Why is carbon dioxide produced when a carbonate react with acids?
Wiki User

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.

∙ 10y agoWhen an acid reacts with a carbonate a substaitution reaction occurs, producing carbonic acid and a corresponding salt. For example, if hydrochloric acid reacts with calcium carbonate the reaction procedes like this:
2HCl + CaCO3 --> CaCl2 + H2CO3 . resulting in the formation of carbonic acid and calcium chloride.
Carbonic acid is unstable and will spontaneously decompose into water and carbon dioxide.

What happens when calcium carbonate reacts with water?
At standard temperature and pressure, calcium carbonate does not react with neutral water, but simply dissolves to a slight extent. If the water is sufficiently acidic as a result of other constituents, carbon dioxide gas can be displaced from the calcium carbonate.
How does an acid react with carbonates?
When acids react with a carbonate or a hydrogencarbonate (or a metal carbonate or a metal hydrogencarbonate) carbon dioxide, water and a salt solution is produced. That is:acid + metal --> carbon dioxide + water + salt solutionAn example is the following ionic equation:CH3COOH(aq) + NaHCO3(s) --> CO2(g) + H2O(l) + Na+(aq) + CH3COO-(aq)You can see this reaction occur when you mix vinegar with some bicarbonate soda (sodium hydrogencarbonate), which is the reaction they use in those little volcanoes you make in the school sand pit ahahaha lol this answer is from Jennifer and by the way She rules jk i suck
What happens when oxygen 2 and carbon is mixed?
Carbon dioxide is a very stable element and only breaks when in solution or when it has enough energy added to break formation. If oxygen and carbon dioxide mix at normal pressure (~1atm) nothing happens, the carbon dioxide will sit underneath the oxygen because it is much heavier then oxygen. If oxygen and carbon dioxide are in a very high pressure vessel they will form a solid at low temperatures, just like any other gas.
What role does calcium carbonate act to prevent acid rain?
CaCo3 is a base, so it neutralizes acids. Thus, CaCo3 can neutralize acids in acid rain. For example, CaCo3 will neutralize HCl by the following equation: 2HCl(aq) +CaCO3(aq) reacts to form CaCl2(aq) + H2O(l) + CO2(g) This gets rid of the acids and makes the acid rain safe for organisms.
Why does the metamorphic rock marble fizz with acid?
Marble fizzes with acid because it is composed of the mineral calcite (calcium carbonate - CaCO3) which reacts with acids to form the gas carbon dioxide and it is the release of the carbon dioxide gas (CO2) that causes the "fizzing" that is observed during the reaction. For example a reaction of calcium carbonate and hydrochloric acid will yield calcium chloride (CaCl2), carbon dioxide and water (H2O) as per the following reaction: CaCO3(s) + 2 HCl(aq) = CaCl2(aq) + CO2(g) + H2O(l)
Why is carbon dioxide produced when carbonate compounds undergo neutralization reactions?
The carbonates are unstable towards acids so the form stable salt, water and carbon dioxide, carbon dioxide is stable than carbonate ion.
What is produced when carbonate reacts with an acid?
Carbonate is CO3(2-) and will react with acids to give off carbon dioxide (CO2), leaving the acid salt of the original carbonate salt.
When stone marble is introduced to acids such as sulfuric and nitric acid. What gases are produced?
Marble is composed of calcium carbonate, the carbonate of this ionic substance reacts with acids to form carbon dioxide and water.
What test is used to assess a mineral based on its reaction with a substance that may or may not produce carbon dioxide bubbles?
Carbon dioxide and water are produced when acids react with carbonate compounds. Therefore, if an acid reacts with a particular mineral and produces carbon dioxide, that mineral contains carbonate compounds.
Produced when acids react with carbonates?
Carbon Dioxide
What gas is produced when acids and carbonates react?
Carbon dioxide(CO2) is the gas that is given off when acids react with carbonates. A salt, water, and carbon dioxide are made in the following reaction acid + metal carbonate ---> salt + water + carbon dioxide.
What is formed when an acid reacts with a carbonate?
Carbon DioxideWhen an acid reacts with a carbonate, the products are:A salt + carbon dioxide + water
What is it that forms when acids react with carbonate compounds?
After this reaction a salt, carbon dioxide and water are formed.
What is produced when a carbonate reacts with an acid?
Carbonate is CO3(2-) and will react with acids to give off carbon dioxide (CO2), leaving the acid salt of the original carbonate salt.
What happens when acid react with compounds made of carbonate?
When acids react with carbonates, carbon dioxide is produced. You can test this by waiting for the chemical reaction to take place and then using a bung to insert the gas into lime water!
Can calcium carbonate neutralize an acid?
Yes. Calcium carbonate can neutralize acids, producing carbon dioxide and a calcium salt that corresponds to the acid.
When acids react with carbonate compounds which gas is released?
Typically whenever carbonate compounds react with acids carbon dioxide gas (CO2) and water (H2O) is formed. For example: 2HNO3 + CaCO3 -----> H2O + CO2 + Ca(NO3)2 nitric acid + calcium carbonate -----> water + carbon dioxide + calcium nitrate
