Answer:
This solution acts as an efficient buffer
Explanation:
the pH of a buffer solution can be described like this:
[acid]=[acetic acid]=
[base]=[sodium acetate]=
replacing,
If we add an acid, pH will decrease a little bit and if we add a base, pH wil increase a little bit.
lets supose that we change the rate by increasing [base] to 0.1, then
and now lets supose that we increase [acid] to 0.1
Big changes in concentration of base or acid doesn´t produce big changes in pH, in that way the mix of sodium acetate with acetic acid is a good buffer solution.
