Question
. Consider the titration of $\mathrm{HF}\left(K_{\mathrm{a}}=6.7 \times 10^{-4}\right)$ with NaOH . What is the pH when a third of the acid has been neutralized?
Step 1
For this problem, we will assume a certain concentration of HF, say \( C \) M. The exact concentration is not given, but it will cancel out later in the calculations. Show more…
