QUESTION:
A 0.054 \(M\) \(\mathrm{HNO_2}\) solution is titrated with a KOH solution. What is \([\mathrm H^+]\) at half way to the equivalence point?
ANSWER:Step 1 of 2
Henderson -Hasselbalch equation is a mathematical expression which can be used to calculate the \(p H\) of buffer solution.
\(p H=p K_{a}+\log \frac{\left[A^{-}\right]}{[H A]}\) ......................... (1)
Here,
\(p K_{a}\) = Concentration of weak monoprotic acid,
\([H A]\) = Concentration of a weak monoprotic acid
\(\left[A^{-}\right]\) - Concentration of its conjugate base.
