For the weak acid-strong base titration, write molecular, ionic, and net ionic reactions for the following processes: a) the hydrolysis (reaction with water) of the weak acid (using the actual formula of your weak acid) b) the neutralization reaction between the weak acid and sodium hydroxide c) the hydrolysis of the conjugate base of the weak acid remember that weak acids and weak bases do not dissociate, so your equations above should reflect this.

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.
