Calculate the pH at the equivalence point in titrating 0.110 M solutions of each of the following with 8.0×10−2 MNaOH.

Question

Part A
hydrobromic acid (HBr)

Answer 1

HBr + NaOH ==> NaBr + H2O

Since HBr is a strong acid and NaOH is a strong base, the material at the end is just a salt in water. The pH of the water will be 7 (at least that's the simple answer and it neglects ionic strength and the Debye-Hueckel theory).
