9. Which of the follow lowing state stements about alpha val lue is (are) correct?(AB) The reiative e equilibrium concea ntrations of the components in a conjugate system (e.g. a conjugate acid/base) are calledslipha (a) values.(AC) The alpha values of a conjugate ncid/base depend on pH and Ka.(AD) Tbe alpha values of a conjugate acid/base are independent of the sum of the analytical concontrations of the acid and itsconjugate base in a buffer solution.(AE) Plotting the alpha values as a function of the pH of the solution shows curves crossing at pH-pKb, wihere Kb i3 the basedissociation constant of the conjugate base,(BC)Since EDTA is a polyprotic acid, its alpha values affect the complex fornation between EDTA and the metal ion (ABE).(BD) Decreasing the o4 value of EDTA favors the fornation of the EDTA-M complex.
