How Do You Calculate Concentrations Without the Ka Value?

[dnt]

question states: Calculate the concentration of all species in a 0.240 M C6H5NH3Cl solution.

first of all how do i know what the reaction is? secondly to i need to know the Ka value for the dIssaciation for this - why isn't it given?

Aniline hydrochloride - salt of a weak base and a strong acid. You will need Kb of aniline or Ka of protonated aniline (hint: these are conjugated acid and base, so if you know one, you can calculate the other).

Most likely Ka was not given to force you to look it up.
