Equilibrium Constants

Postby melodyzaki2E » Fri Nov 30, 2018 7:41 pm

How do we find the equilibrium constants for weak acids/bases? Is it different from strong acids/bases?

From my understanding, we do not need to do calculations involving weak acids or bases. In general, however, the value of the constant remains the same: the concentrations of the conjugate acids and bases will decrease. This is because for weak acids and bases, there is incomplete disassociation, hence lessening product concentrations.

Strong acids/base reactions go so far towards dissociation we assume they completely dissociate, so no equilibrium constant needs to be solved for. (There are basically no reactants left)
