Strong Acids/Bases

Postby Jessica Beroukhim 3K » Tue Dec 05, 2017 5:50 pm

Do strong acids have a Ka? Do strong bases have a Kb?

Their equilibrium constants are basically infinity since there are hardly any reactants, so no

To clarify, we don't calculate a Ka or Kb because we assume for strong acids and bases are 100% ionized in a solution, because the equilibrium concentration otherwise is so small it becomes useless in calculations. That would mean that for example:

0.1M HCL would 100% ionize to form 0.1M H3O+ and 0.1M Cl-

Strong acids and bases do not have Ka and Kb values because they completely dissociate in water. Ka and Ka are used to describe only weak acids, but pH values can be used to describe both strong and weak acids.
