WebbKafor HCN is 5.8 x 10-10. First, write the equation for the dissolving process, and examine each ion formed to determine whether the salt is an acidic, basic, or neutral salt. KCN(s) --> K+(aq) + CN-(aq) K+is a neutral ion and CN-is a basic ion. KCN is a basic salt. Second, write the equation for the reaction of the ion with water and the WebbBecause the pKa value cited is for a temperature of 25°C, we can use Equation 16.5.16: pKa + pKb = pKw = 14.00. Substituting the pKa and solving for the pKb, 4.83 + pKb = 14.00 pKb = 14.00 − 4.83 = 9.17 Because pKb = − logKb, Kb is 10 − 9.17 = 6.8 × 10 − 10.
