What does a pKa of 50 mean?
So, strong acids have small pKa's (-15 — 1); they are unstable intact in water; they have small affinity for their protons and want to dissociate from them. Weak acids have large pKa's (2 — 50); they are stable because they have high affinity for their protons and want to stay bound to them.
