Answer:

Acetic acid neutralizes added base, and sodium acetate neutralizes added acid.

Explanation:

Acetic acid is the acid that will dissociate to release H⁺ ion which will react and neutralize the  added base.  

CH₃COOH →  H⁺ + CH₃COO⁻

H⁺ + OH⁻ → H₂O

Sodium acetate will dissociate to release the acetate ion (CH₃COO⁻) which will react and neutralize the added acid.  

CH₃COONa →  Na⁺ + CH₃COO⁻

H⁺ + CH₃COO⁻ → CH₃COOH

Based on the information given, the correct option will be A. Acetic acid neutralizes added base, and sodium acetate neutralizes added acid.

  • An acetic acid simply means the acid that will dissociate to release H⁺ ion which will react and neutralize the added base.  

  • Acetic acid is used for manufacturing acetic anhydride, cellulose acetate, acetic esters, plastics, dyes, etc.

In conclusion, the correct option is A.
