<p>What is the answer to part C? Also, how do you do part C? I'm rusty.</p>
<p>To find the volume of titrant added at the equivalence point, just use MV=MV (aka CV=CV): (Concentration of acid)(Volume of acid)=(Concentration of base)(volume of base). You can calculate it easily.</p>
<p>The answer to the second part is that it will be basic. Ba(OH)2 is a strong base, HOBr is a weak acid. When titrating a weak acid with strong base, pH at equiv. pt. will be basic. When titrating weak base with a strong acid, pH will be acidic. When titrating strong acid with strong base (or vice versa) pH will be neutral. Don't worry about weak/weak.</p>
