Draw two titration curves, both of a weak base with a strong acid. The first has a pKA of 9.4 and a low buffer strength; the second has a pKA of 8.0 and a strong buffer strength.
Homework Answers
Answer: We draw as follows two titration curves, both of a weak base with a strong acid. The first has a pKa of 9.4 and a low buffer strength; the second has a pKa of 8.0 and a strong buffer strength.
Titration curve 1 (of weak base with a strong acid having pKa of 9.4 and a low buffer strength).
Titration curve 2 (of weak base with a strong acid having pKa of 8.0 and a strong buffer strength).

It's a weak acid strong base titration
Experiment 4: Identification of an unknown acid by titration Page 2 of 15 Background In this experiment, you will use both qualitative and quantitative properties to determine an unknown acid's identity and concentration. To do this analysis, you will perform a titration of your unknown acid sample-specifically a potentiometric titration where you use a pH meter and record pH values during the titration, combined with a visual titration using a color indi- cator...

1. A weak acid (benzoic acid) is titrated with a strong base such as sodium hydroxide. Determine the pH at the half equivalence point of the titration. The Ka of the weak acid is 6.3 x 10-5. 2.Calculate the pH of a buffer made from 0.6 M HNO2 and 0.5 M NaNO2. Ka = 4.5 x 10-5 pKa = 4.3 Answer with one digit after the decimal place (e.g. 2.1) Hint: HNO2 is a weak acid. NaNO2 forms the conjugate...
