Ka/b and pKa/b relationship

[Jose Torres]

What is the relationship between Ka and pKb? Does pKb go down if Ka goes up? Also, what pKa and Ka produce a strong conjugate base?

[Jordan Lo 2A]

pKa and pKb are the -log of Ka and Kb. As the exponent of the K becomes more negative, pKa or b increases

[Alysa Rallistan 2G]

It's better to remember the relation between Ka and pKa (vice versa with Kb) but the smaller the value of Ka, then the larger the value of pKa and thus the weaker the acid, if a weak acid has a small Ka value it's conjugate base will have a large Kb value
