Write Sodium carbonate reacts with acetic acid, the products are carbon dioxide ,water ,and sodium acetate ?
The Correct Answer and Explanation is:
When sodium carbonate reacts with acetic acid, a chemical reaction occurs that produces three products: carbon dioxide (CO2), water (H2O), and sodium acetate (CH3COONa). Here’s a step-by-step breakdown of the reaction:
The balanced chemical equation for this reaction is:Na2CO3+2CH3COOH→2CH3COONa+H2O+CO2Na_2CO_3 + 2CH_3COOH \rightarrow 2CH_3COONa + H_2O + CO_2Na2CO3+2CH3COOH→2CH3COONa+H2O+CO2
Explanation:
- Sodium Carbonate (Na2CO3): Sodium carbonate is a basic compound made up of sodium ions (Na⁺) and carbonate ions (CO₃²⁻). It is commonly used in cleaning agents, water treatment, and various chemical reactions.
- Acetic Acid (CH3COOH): Acetic acid is a weak acid that is the main component of vinegar. It contains hydrogen ions (H⁺) that can react with bases.
- The Reaction: When sodium carbonate reacts with acetic acid, the carbonate ions (CO₃²⁻) from sodium carbonate interact with the hydrogen ions (H⁺) from acetic acid, forming carbonic acid (H2CO3). Carbonic acid is unstable and quickly decomposes into carbon dioxide (CO2) and water (H2O).
- Sodium Acetate (CH3COONa): The sodium ions (Na⁺) from sodium carbonate combine with the acetate ions (CH₃COO⁻) from acetic acid to form sodium acetate (CH3COONa), a salt.
Products:
- Carbon Dioxide (CO2): This gas is released as bubbles during the reaction, similar to the fizzing you see when baking soda reacts with vinegar.
- Water (H2O): Water is formed as a byproduct of the acid-base reaction.
- Sodium Acetate (CH3COONa): This is the salt formed when the sodium ions from sodium carbonate combine with the acetate ions from acetic acid.
This reaction is an example of an acid-base reaction where a weak acid (acetic acid) reacts with a base (sodium carbonate), resulting in the formation of a salt, water, and carbon dioxide. The fizzing or effervescence observed during this reaction is due to the release of carbon dioxide gas.
