eq constants for acids

Postby rachana_korapati3C » Mon Jan 28, 2019 10:02 am

why do strong acids not have equilibrium constants? is it because the acid dissociates completely?

Strong acids do have Ka values, extremely large ones that, for the purpose of stoichiometry, the value is considered infinity. This is because strong acids will in theory dissolve completely

Strong acids do not have equilibrium constants because they dissociate completely.

Strong acids completely dissociate in solution. Because of this, their Ka value would be so large that for this class we just approximate that to be infinity.

Yes, because strong acids dissociate completely
