(C) For an acidic buffer,the Henderson-Hasselbalch equation is given by: $pH = pK_{a} + \log \frac{[Salt]}{[Acid]}$ Given: $pH = 5.5$ $pK_{a} = 4.5$ $[Acid] = 0.1 \ M$ Substituting the values: $5.5 = 4.5 + \log \frac{[Salt]}{0.1}$ $5.5 - 4.5 = \log \frac{[Salt]}{0.1}$ $1 = \log \frac{[Salt]}{0.1}$ Taking antilog on both sides: $10^{1} = \frac{[Salt]}{0.1}$ $[Salt] = 10 \times 0.1 = 1.0 \ M$
