Answer to Question #56239 in Inorganic Chemistry for chaloni
What does it mean to say that an acid is a strong acid? How is a strong acid different from a weak acid?
Strength of the acid is determined by its dissociation, more exactly – by its dissociation constant:
AxBx = xA + yB
Kd = [A]x [B]y / [AxBy]
Strong acids dissociate almost fully, Kd>1*10-3. Weak acids dissociate only partially, Kd <1*-3 respectively.
