Write Sodium carbonate reacts with acetic acid, the products are carbon dioxide ,water ,and sodium acetate ?
The Correct Answer and Explanation is:
Yes, when sodium carbonate (Na2CO3) reacts with acetic acid (CH3COOH), the products formed are carbon dioxide (CO2), water (H2O), and sodium acetate (NaCH3COO). Here’s a breakdown of the chemical reaction:
The reaction between sodium carbonate and acetic acid is an acid-base reaction. Sodium carbonate, a basic compound, reacts with the acetic acid, which is a weak acid. The overall reaction can be represented as:
Na2CO3(aq)+2CH3COOH(aq)→2CH3COONa(aq)+H2O(l)+CO2(g)\text{Na}_2\text{CO}_3 (aq) + 2 \text{CH}_3\text{COOH} (aq) \rightarrow 2 \text{CH}_3\text{COONa} (aq) + H_2O (l) + CO_2 (g)Na2CO3(aq)+2CH3COOH(aq)→2CH3COONa(aq)+H2O(l)+CO2(g)
In this reaction:
- Carbonate (CO3^2-) from sodium carbonate reacts with the protons (H+) from acetic acid, forming carbonic acid (H2CO3), which is unstable.
- Carbonic acid quickly decomposes into carbon dioxide (CO2) and water (H2O).
- Sodium acetate (CH3COONa) is formed as a result of the reaction between the sodium ion (Na+) from sodium carbonate and the acetate ion (CH3COO^-) from acetic acid.
The carbon dioxide gas released during the reaction is what gives the characteristic bubbling or effervescence, commonly observed in reactions where carbonates react with acids. This is a sign that a gas is being produced. The release of carbon dioxide is due to the breakdown of carbonic acid, which is unstable and decomposes under normal conditions.
The reaction is also an example of a double displacement reaction, where the cations and anions of the two reactants switch places to form new products. This type of reaction is commonly encountered when acids react with carbonates or bicarbonates.
