Webb7 sep. 2024 · Since HCl is a strong acid, the value of Ka turns out to be very large, that is, Ka=1071=107 (approx.) How do you find the Ka from a titration curve? The equation for the pKa is pKa = – log (Ka). Therefore, 10 ^ (-pKa) = Ka. If the pKa is 7, then 10 ^ -7 = 1.0 x 10 ^ -7. The value of Ka on the titration graph is Ka = 1.0 x 10 ^ -7.
