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

The greater the K_a 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 K_a 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
H_2SO_4
HClO_4
HNO_3
