How do you determine the pka value of naphthalene?

Answer 1

Use a method called titration, where a known concentration of either a strong acid (to measure a weak base) or a strong base (to measure a weak acid) is slowly added to a solution of the unknown compound. By measuring the pH of the solution as you do the titration, and by measuring the volume of the known solution that you added to the unknown, you can determine the pKa of the unknown compound.

how can i determine pka value if pH is given?

Answer 2

The pKa value of naphthalene can be determined through experimental methods such as potentiometric titration or using computational chemistry techniques to predict the acidity of the compound based on its molecular structure. Naphthalene is a weak acid with a pKa estimated to be around 10.4, but it is generally considered non-ionizable under typical conditions.

Answer 3

naphthalene is neutral.
