We are asked to answer each of the following questions regarding these two titrations.
Part A
At the equivalence point, moles of acid = moles of base.
We use the equation below to calculate volume:
Vb = 10 mL KOH
10 mL 0.200 M KOH will be needed to titrate 20 mL 0.100 M HCl
Part B
At the equivalence point, moles of acid = moles of base.
We use the equation below to calculate volume:
Two 20.0mL samples, one 0.100 M HCl and the other 0.100 M HF, were titrated with 0.200 M KOH. Answer each of the following questions regarding these two titrations.
Part A
What is the volume of added base at the equivalence point for HCl?
Part B
What is the volume of added base at the equivalence point for HF?
Part C
Predict whether the pH at the equivalence point for each titration will be acidic, basic, or neutral.
Part D
Predict which titration curve will have the lowest initial pH.
