t Relating pKa and pKb Learning Goal: 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 dissociate in solution is given by its acid- ionization consianf, Ka. For the generic weak acid, HA, HA(ag) O in solution is Similarly, the degree to which a weak base reacts given by hasp ionizabon Kuo Far the genArir. k ha ng pK Part A ed X-28 being tested by eak acid, but because of security concerns, the actual chemical form is active in PALE 1.071 ncorrect Try Again: 5 ts remain pany, Pha :arch lechri al Pha that X-281 must remain top secret Ihe company is interested inthe drugs K. value becau only the dissociated orm of the hepHofthe Sululion is determined be 240. What is ule BK DIX X-281?Explanation / Answer
We know that
pH = [ pKa - logC]/2 where C is concentration
2.4 = [ pKa - log (0.093)]/2
pKa - log (0.093) = 4.8
pKa = 3.77
