Just to clarify,
the larger the Ka, the stronger the acid
and
the lower the pKa, the stronger the acid?
pKa, Ka, and relative acid strength

Re: pKa, Ka, and relative acid strength
Yes, you are right.
The larger the Ka, the stronger the acid. The smaller the pKa, the stronger the acid
And the same applies for bases, the larger the Kb, the stronger the base. The smaller the pKb, the stronger the base
The larger the Ka, the stronger the acid. The smaller the pKa, the stronger the acid
And the same applies for bases, the larger the Kb, the stronger the base. The smaller the pKb, the stronger the base

Re: pKa, Ka, and relative acid strength
You are correct!
I believe it is the same for bases; decreasing pKb and increasing Kb will correspond to increasing base strength.
An example of this concept can be found in 12.39 in the 6th edition.

Re: pKa, Ka, and relative acid strength
You're right! Because pKa is the -log of Ka, when Ka is larger and the acid is stronger, pKa is decreased.
