Concept explainers

Acid Base Titration

An acid-base titration is the method of quantitative analysis for determining the concentration of an acid and base by exactly neutralizing it with a standard solution of base or acid having known concentration.

Question

what is the solubility switch rule? is basic solution in organic layer when pH < pKa? why would aniline be in organic layer when pH > pKa then?

N
OH
O₂N
pKa = 3.4
pKa = 7.0
