QUESTION

is it true that the sum of pKa and pKb is always equal to 14 at all temperature for an acid? if not why?

ANSWER

TRUE

B e c a u s e:-

➡️Therefore, at the half-equivalence point, the pH is equal to the pKa. A plot of the titration curve allows the equivalence point to be determined. At exactly one- half the volume of the equivalence point, the measured pH is equal to pKa as illustrated in Figure 3.
