basic Titration question?

Question

What information does acid/base titrations give? how does the acid titration allow you to determine the solubility constant in experiment?

Answer 1

The information gives you the molarity of the acid or the base you want, knowing molarity and amount necessry to neutralization.
When you have a salt AB poorly soluble ,you have

Ksp = [A-][B+] where the value in brackets mean concentrations, you determined by titration

Answer 2

You can determine the molecular weight of an acid by titration. You can determine the Ka of a weak acid by titration. You can also determine if an acid is diprotic or even triprotic (more difficult than diprotic).

For Ksp, imagine a saturated solution of Ba(OH)2. Now, titrate it with H2SO4. You would precipitate BaSO4. Knowing the weight of the BaSO4 precipitated allows you to know the Ba2+ in solution. From this, you can determine the OH- in solution, thus be able to calculate the Ksp. However, you must know the formula of the substance before doing this.
