Conductimetric Determination of Ka: Since the conductance of a solution of the weak acid HA is a measure of the concentration of H+ and A- ions, a measurement of conductance of a solution of known [HA] concentration should allow us to calculate Ka, and indeed this method has contributed greatly to our knowledge ...

Ka is defined for the reaction ... A larger equilibrium constant means that the reaction has a greater tendency to drive towards the products side (more H3O+ and A–, less HA). Another way of saying this is that the acid has a stronger tendency to donate its H+, which is the definition of a stronger acid...
