Document Summary
Cl- does not accept proton from h3o+: if an acid is weak its conjugate base is relatively strong. Hf remains mainly unionized: there are six strong acids, 1. ) Acid and base strength: a small value of ka indicates that the numerator is smaller than the denominator. At equilibrium, reactants are favored, and thus the weak acid dissociates only to a small extent. The ratio of the two should be within 5%: when working with acids (or bases) look closely at the ka (kb). If the ratio of the initial concentration of the acid to the ka is greater than 100, you may use the x is small approximation. Strong bases: the little b : group i hydroxides, group ii hydroxides except for be(oh)2 and mg(oh)2, francium and radium are rare and radioactive, so we will not concern ourselves with them. Ionization constants of bases: in general, a weak base b with the base ionization.
