pKa/pKb

[Jasleen Kahlon]

I don't fully understand how pKa and pKb are related to pH and Ka/Kb. Can someone please explain what pKa and pKb are?

[Ariana Iranmahboub1G]

pKa and pKa are the -log of Ka/Kb. You can convert pH to Ka using 10^-ph. You can do the same with pOH by converting pOH to Kb using 10^-pOH.

[Myka G 1l]

pKb is the -log(Kb) and pKa is the -log(Ka). pH is related to pKa through the Henderson Hasselbach equation -> pH= log[A-]/[HA] + pKa

pKa and pKa are the -log of Ka/Kb. You can convert pH to Ka using 10^-ph. You can do the same with pOH by converting pOH to Kb using 10^-pOH.

And Just for clarification they are related to pH because they are dissociation constants, they show how much an acid or base dissociate which then determines the strength of the acid or base which is reflected in its pH value. Stronger acids and bases dissociate more than weak acids and bases.
