Titration curve, how to find equivalence point
If you have a graphed titration curve and have points near the equivalence point like
6.85 pH at 54.60mL titrant added and
8.01 pH at 54.73mL titrant added
is there any good way to find a more ...

Titration of alpha-amino acid with strong base
Question:
$\mathrm{50~ml}$ of the conjugate acid $\ce{H3N+CH(R)COOH}$ of an $\alpha$-amino acid required $\mathrm{30~ml}$ of $\mathrm{0.1~M}~\ce{NaOH}$ to completely convert into the dipolar ion $\ce{...

Determine the pKa of a diprotic acid by titration (if pKa1 is similar to pKa2)
Determining the acidity constants of a diprotic acid (in my case, tartaric acid) by titration with NaOH and pH-meter is not possible if pKa2 - pKa1 < 2.
This is because there are no "pH jumps&...

Equivalence point pH derivation of a tribasic acid
Considering $\pu{100 mL} \ \pu{0.1 M} \ \ce{H3A}$ and $\pu{0.1 M} \ \ce{NaOH}$ titration curve:
I understood the half equivalence points, but couldn't understand the reason why $\mathrm{pH} = \frac{1}...

Does the acid dissociation constant fluctuate or stay constant during titration?
I'm doing titration experiment, where I record the volume of base added and the pH value, then use these two variable to make a titration graph. I'm suppose to extrapolate any data needed from the ...

Titration of a weak acid with a strong base
I recently learned that when titrating a strong base like NaOH into a weak acid, like Acetic Acid, a buffer region/zone develops and can be illustrated as follows:
CH₃COOH + OH⁻→ CH₃COO⁻ + H₂O
I've ...

Why are buffer solutions not neutral
I am very confused about buffer solutions and I have lots of ideas about them which don’t integrate together so I really can’t tell which are correct and which are wrong. That being the case it’s ...
