\( \mathrm{HCH}_{3} \mathrm{CO}_{2} \) is a weak acid.

Solución

To determine the type of chemical \( \mathrm{HCH}_{3} \mathrm{CO}_{2} \) (which is acetic acid, \( \mathrm{CH}_{3} \mathrm{COOH} \)) involved in the reaction: \[ \mathrm{CH}_{3} \mathrm{CO}_{2} + \mathrm{H}_{2} \mathrm{O} \leftrightarrows \mathrm{CH}_{3} \mathrm{CO}^{2-} + \mathrm{H}_{3} \mathrm{O}^{+} \] we need to analyze the properties of acetic acid. 1. **Acetic Acid as a Weak Acid**: Acetic acid (\( \mathrm{CH}_{3} \mathrm{COOH} \)) is known to be a weak acid. It does not completely dissociate in water, which is characteristic of weak acids. 2. **Reaction Analysis**: In the given reaction, acetic acid donates a proton (\( \mathrm{H}^+ \)) to water, forming the acetate ion (\( \mathrm{CH}_{3} \mathrm{CO}^{-} \)) and hydronium ion (\( \mathrm{H}_{3} \mathrm{O}^{+} \)). This behavior is typical of weak acids. 3. **Conclusion**: Since acetic acid does not fully dissociate in solution and establishes an equilibrium with its ions, it is classified as a weak acid. Thus, the type of chemical \( \mathrm{HCH}_{3} \mathrm{CO}_{2} \) involved in this reaction is a **Weak Acid**.

The compound \( \mathrm{HCH}_{3} \mathrm{CO}_{2} \), also known as acetic acid, is classified as a weak acid. This means it only partially dissociates in water, which is reflected in the equilibrium reaction where it forms acetate ions (\( \mathrm{CH}_{3} \mathrm{CO}^{2-} \)) and hydronium ions (\( \mathrm{H}_{3} \mathrm{O}^{+} \)). In real-world applications, understanding weak acids like acetic acid is crucial in various fields, including food preservation, where it is used as a flavoring agent and preservative. It's also widely used in the production of vinegar, which is beloved by chefs and food enthusiasts for its ability to enhance flavors and balance dishes!
