When you mixand separate CaCO3 and SiO2 with acetic acid-vinegar, it is a chemical reaction. It bubbles and CO2 is produced. What property of CaCO3 causes this to happen?
Could you explain this to me pls. I am guessing the acetic acid reacts with one of the acetic acid, but how and why? Is there a formula that could help me understand? What property of CaCO3 causes this to happen?
Thank you.
It is a chemical property because the CaCO3 is changed into something different. The equation is
CaCO3 + 2HC2H3O2 ==> Ca(C2H3O2)2 + CO2 + H2O
why is it necessary to heat alum
The bubbling and production of carbon dioxide (CO2) when CaCO3 (calcium carbonate) reacts with acetic acid in vinegar is indeed a chemical reaction. This reaction can be explained by understanding the properties of CaCO3 and acetic acid.
The chemical formula for calcium carbonate is CaCO3, while acetic acid is represented by the formula CH3COOH. When these two substances come into contact, a reaction occurs due to the reaction between calcium carbonate and acetic acid.
The key property of CaCO3 that causes this reaction is its ability to undergo a chemical reaction with acids. CaCO3 is classified as a basic compound or an alkaline substance, which means it can react with acids to form new products.
In the case of the reaction with acetic acid, the chemical equation can be represented as follows:
CaCO3 + 2CH3COOH -> Ca(CH3COO)2 + CO2 + H2O
In this equation, CaCO3 reacts with acetic acid (CH3COOH) to produce calcium acetate (Ca(CH3COO)2), carbon dioxide (CO2), and water (H2O). The bubbling observed is due to the release of CO2 gas.
The reaction occurs because the acidic nature of acetic acid (CH3COOH) breaks down the calcium carbonate (CaCO3) into calcium ions (Ca2+) and carbonate ions (CO32-). These ions then combine with the acetic acid to form calcium acetate. Additionally, the release of carbon dioxide gas (CO2) is a result of the reaction between the carbonate ions and the acetic acid.
So, to summarize, the property of CaCO3 that causes the reaction when mixed with acetic acid is its nature as a basic compound, which allows it to undergo a reaction with acids.
