The ratio of [sodium acetate] to [acetic acid] in a buffer solution is 0.30.
Henderson–Hasselbalch equation: pH = pKa + log(cs/ck)
pH = 4.25; pH of buffer solution
pKa = -log(1.7 × 10−5) = 4.77
4.25 = 4.77 + log(cs/ck)
log(cs/ck) =4.25 - 4.77 = -0.52
cs/ck = 10∧(-0.52) = 0.30; ratio of sodium acetate to acetic acid
A buffer can be defined as a substance that prevents the pH of a solution from changing by either releasing or absorbing H⁺ in a solution.
Buffer is a solution that can resist pH change upon the addition of an acidic or basic components and it is able to neutralize small amounts of added acid or base, pH of the solution is relatively stable.
