Which statement describes the action of a buffer composed of acetic acid and sodium acetate?

Which statement describes the action of a buffer composed of acetic acid and sodium acetate?

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

How do you make a buffer solution with acetic acid and sodium acetate?

  1. Prepare 800 mL of distilled water in a suitable container.
  2. Add 7.721 g of Sodium Acetate to the solution.
  3. Add 0.353 g of Acetic Acid to the solution.
  4. Adjust solution to final desired pH using HCl or NaOH.

Which statement describes the action of a buffer composed of formic acid and sodium formate?

Formic acid neutralizes added base, and sodium formate neutralizes added acid. Both components, formic acid and sodium formate, neutralize added acid. Both components, formic acid and sodium formate, neutralize added base.

Which statement describes the action of a buffer composed of citric acid and sodium citrate?

(c) Due to acidic nature of citric acid, it neutralizes with a base. Sodium citrate is a base as it has negative charge and hence it reacts with an acid to neutralize. Therefore, the correct option is (c) (d) Sodium citrate is base hence it neutralizes with an acid.

Which statement describes the action of a buffer composed of propionic acid and sodium propionate?

Question: Which Statement Describes The Action Of A Buffer Composed Of Propionic Acid (CH3H2COOH) And Sodium Propionate (NaCH3CH2COO) ? Both Components, Propionic Acid And Sodium Propionate, Neutralize Added Base. Sodium Propionate Neutralizes Added Base, And Propionic Acid Neutralizes Added Acid.

Why does the pH of the buffer consisting of acetic acid and sodium acetate not change when a few drops of HCl are added to it?

Unlike in the case of an acid, base, or salt solution, the hydronium ion concentration of a buffer solution does not change greatly when a small amount of acid or base is added to the buffer solution. The base (or acid) in the buffer reacts with the added acid (or base).

Which one of the following is an example of buffer solution?

Sodium bicarbonate and carbonic acid.

Is HClO4 and naclo4 a buffer solution?

(d) HClO4 is a strong acid and hence this is not a buffer system.
