Waht are the domianan spaces ina solution of Benzoic acid and NaOH at pH 4.5?
Does the solution at pH= 4.5 constitute a buffer?
What are the major speceis in solution during the titration of citric acid with a strong base?
Type your anserwes please.
Thanks
pKa = 4.20
then
there is plenty of conjguate
[Benzoate] > [Benzoic Acid]
b)
when titrating citric acid, the major solution is citrate

Calculate the pH during titration of 75.0mL of 0.100M benzoic acid by 0.100M NaOH before the addition of NaOH and after 20mL NaOH are added. Ka=6.3x10^-5
What is the pH of a buffer solution made by mixing 0.1 M benzoic acid and 0.15 M of its conjugate base, sodium benzoate. Ka = 6.5x10-5 for benzoic acid.
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...
A benzoic acid/potassium benzoate buffer solution has a pH = 4.25. The concentration of benzoic acid (C6H5COOH, Ka = 6.5 × 10-5) in the solution is 0.54 M. What is the concentration of potassium benzoate (KC6H5COO, Kb = 1.5 × 10-10) in this buffer solution?
