Problem 11-4

Metal ion buffers. By analogy to a hydrogen ion buffer, a metal ion buffer tends to maintain a particular metal ion concentration in solution. A mixture of the acid HA and its conjugate base A maintains [H] defined by the equation Ka [A][H]/[HA]. A mixture of CaY2 and Y4 serves as a Ca2 buffer governed by the equation 1/Kf [EDTA][Ca2]/[CaY2]. How many grams of Na2EDTA 2H2O (FM 372.23) should be mixed with 1.95 g of Ca(NO3)2 2H2O (FM 200.12) in a 500-mL volumetric flask to give a buffer with pCa2 = 9.00 at pH 9.00? 11-5. Pu
