Acetic acid, also known as ethanoic acid, is a mild acid. However, it still displays acidic properties, one of them being...
metal carbonate + acid ---> salt + water + carbon dioxide
So when calcium carbonate is added to ethanoic acid, the following reaction occurs.
CaCO3+2CH3COO-H+ ---> (CH3COO-)2Ca2++H2O+CO2
The acetic acid must contain a little water for the reaction to proceed. Calcium carbonate and acetic acid combine in a neutralization reaction to form water, calcium acetate, and carbon dioxide. CaCO3 + 2CH3COOH = Ca(CH3COO)2 + CO2 + H2O
Vinegar is acidic (acetic acid) and reacts with the calcium carbonate in the eggshell, breaking it down and releasing carbon dioxide gas in a chemical reaction. This reaction dissolves the calcium carbonate in the eggshell, leaving it soft and disintegrated.
The rubber egg experiment involves soaking an egg in vinegar, which causes the calcium carbonate in the eggshell to react with the acetic acid in vinegar to produce calcium acetate, carbon dioxide, and water. This reaction dissolves the eggshell, leaving behind a rubbery membrane that gives the appearance of a rubber egg.
CaCO3 + 2 CH3COOH ------------- Ca(CH3COO)2 + H2O + CO2
Calcium carbonate is added to neutralize the excess of acetic acid which remain after the precipitation of casein.
Calcium acetate is formed when acetic acid reacts with calcium carbonate. This reaction produces calcium acetate, water, and carbon dioxide.
When calcium carbonate is added to acetic acid, carbon dioxide gas will evolve as a result of the reaction. This is because acetic acid will react with the calcium carbonate to form calcium acetate, water, and carbon dioxide.
The component of vinegar that reacts with the calcite is acetic acid. The acid reacts with calcium carbonate to produce water, carbon dioxide, and calcium acetate.
The acetic acid must contain a little water for the reaction to proceed. Calcium carbonate and acetic acid combine in a neutralization reaction to form water, calcium acetate, and carbon dioxide. CaCO3 + 2CH3COOH = Ca(CH3COO)2 + CO2 + H2O
it bubbles up. and at that point the calcium carbonate under goes a change in color
The reaction between Chalk and Vinegar creates carbon dioxide. Chalk is calcium carbonate and when vinegar is poured on it. It is prepared from water and acetic acid it should fizz up as the oxygen in the acetic acid combines with the calcium carbonate. The foams are carbon dioxide that is formed when the oxygen from the acetic acid links with the carbon from the calcium carbonate.
Examples: hydrochloric acid, nitric acid, acetic acid, etc.
Vinegar is a solution of a carboxylic acid (acetic acid) which means that most metal compounds (particulaly alkaline metal compounds found in group 1 in the periodic table) will react with it to produce salts, carbon dioxide and water. Sodium Carbonate is a common example of a alkaline metal compound that reacts readily with vinegar.
Before dilute acetic acid is added to calcium carbonate, you would observe that the calcium carbonate is a white solid. There may be no visible reaction or bubbling occurring prior to the addition of the acid.
The shell (Calcium carbonate) dissolves in acetic acid and forms water and carbon dioxide. CaCO3 + 2 CH3COOH --> Ca(CH3COO)2 + H2O + CO2
The balanced chemical equation for acetic acid (CH3COOH) reacting with calcium carbonate (CaCO3) to yield calcium acetate (Ca(CH3COO)2) and carbon dioxide (CO2) is: 2CH3COOH + CaCO3 → Ca(CH3COO)2 + CO2 + H2O
CaCO3 + 2 HCl = CaCl2 + CO2 + H2O Calcium Carbonate + 2 Hydrochloric Acid = Calcium Chloride + Carbon Dioxide(which is a gas) + Water CaCO3 + 2 CH3COOH = Ca(CH3COO)2 + CO2 + H2O Calcium Carbonate + 2 Acetic Acid (Vinegar) = Calcium Acetate + Carbon Dioxide + Water In these equations it is obvious that Carbon Dioxide is mostly released after an reaction of calcium carbonate with some acids.
