Here is what I understand of the concept.


The larger the Ka value, the strong the acid.

So acid with Ka of 3.9 x 10^-3 is weaker than acid with Ka of 3.9 x 10^-2

The Ka values sort of throw me off.

Would like to confirm my understanding of this concept.


Thanks

Your understanding is OK.

Also, the Shriver/Atkins textbook defines strong acids as those with pKa<0, or Ka > 1 (usually Ka >>1)
Weak acids are those with pKa>0, or Ka < 1 (usually Ka<<1)

The relative strength can be estimated by comparing Ka's
