Question

Two 24.0 ml samples, one 0.100 moll-1 HCl and the other 0.100 moll-1 HF, were titrated with 0.200 moll-1 KOH. What is the volume of added base at the equivalence point for HF?

Answer 1

In a titration, the volume of added base at the equivalence point for HF can be determined by using the stoichiometry of the balanced chemical equation for the reaction between HF and KOH.

Step-by-step explanation:

In a titration, the volume of added base at the equivalence point for HF can be determined by using the stoichiometry of the balanced chemical equation for the reaction between HF and KOH. The balanced chemical equation is:

HF + KOH → KF + H2O

From the equation, we can see that 1 mole of HF reacts with 1 mole of KOH. Therefore, the volume of added base at the equivalence point for HF will be the same as the volume of HF.
