Percent ionization for a weak acid (ha) is determined by the following formula: percent ionization=[ha] ionized[ha] initial×100%for strong acids, ionization is nearly complete (100%) at most concentrations. however, for weak acids, the percent ionization changes significantly with concentration. the more diluted the acid is, the greater percent ionization.a certain weak acid, ha, has a ka value of 9.4×10? 7.part acalculate the percent ionization of ha in a 0.10 m solution.part bcalculate the percent ionization of ha in a 0.010 m solution

To understand the relation between the strength of an acid or a base and its pka and pkb values. the degree to which a weak acid dissociates in solution is given by its acid-ionization constant, ka. for the generic weak acid, ha, ha(aq)⇌a−(aq)+h+(aq) and the acid-ionization constant is given by ka=[a−][h+][ha] similarly, the degree to which a weak base reacts with h2o in solution is given by its base-ionization constant, kb. for the generic weak base, b, b(aq)+h2o(l)⇌bh+(aq)+oh−(aq) and the base-ionization constant is given by kb=[bh+][oh−][b] what is pkb of the conjugate base of x-281? (assume 25 ∘c.) express your answer numerically.
