How do the Ka values for weak and strong acids compare?

The greater the Ka value for an acid is relative to the strength of the acid, or the magnitude at which it will disassociate in water.

The closer the Ka value is to one the stronger it is (the term "strong acid" means that it completely disassociates).

If you can remember the 6 strong acids you'll know that all other acids are weak:
HCl
HBr
HI
H2SO4
HClO4
HNO3
