Strong acid-> strong or conjugate base?

Postby Chem_Mod » Sun Aug 21, 2011 11:58 am

If there is a strong acid, then does that mean it has a strong or weak conjugate base? And how about for the strong base ?

No. If you have a strong acid, that means that it is totally deprotonated in solution. A strong base would be completely protonated in solution-- so the conjugate of either would have to be weak or else, by definition, the conjugate acid or base would completely ionize again to form the original acid/base.

So it's as if strong acids and bases don't have conjugate acids/bases?

They have conjugate acids/bases, they are just extremely weak. Acid and conjugate base strength are inversely proportional. HBr is a strong acid, so its conjugate base, Br-, is so weak that it is an ineffective base.
