Question

write the equation for the reaction that occurs when hcl is added to an acetic acid/sodium acetate buffer solution (which of the two buffer components will the hcl react with?)

Answer 1

HCl will react with the acetate ion from sodium acetate in the acetic acid/sodium acetate buffer solution.

Step-by-step explanation:

When HCl is added to an acetic acid/sodium acetate buffer solution, the HCl will react with the acetate ion from sodium acetate.

The reaction that occurs is:
HCl(aq) + CH3COO-(aq) → CH3COOH(aq) + Cl-

When a small amount of an acid or a base is added, the buffer solution's purpose is to resist changes in pH. For this situation, the acidic corrosive/sodium acetic acid derivation cradle is intended to keep a steady pH. At the point when HCl is added, the sodium acetic acid derivation part of the support responds with the HCl to frame sodium chloride and acidic corrosive, assisting with keeping up with the pH of the arrangement.

It is essential to keep in mind that the buffer's acetic acid component does not directly react with the HCl. All things being equal, the sodium acetic acid derivation goes about as the base in the response, killing the additional corrosive (HCl) and forestalling huge changes in pH.
