How To Calculate Ka From Molarity

How do you calculate Ka from molarity and concentration?

https://scienceoxygen.com/how-do-you-calculate-ka-from-molarity-and-concentration/

Calculate the pKa with the formula pKa = -log (Ka). For example, pKa = -log (1.82 x 10^-4) = 3.74. What is the formula for Ka? Ka and Kb values measure how well an acid or base dissociates. Higher values of Ka or Kb mean higher strength. General Ka …
