Question

metal ion:                   Sc3+     Co3+           Fe3+     Ga3+

 log K1(EDTA):           23.1     41.4            25.5     21.5    

i) The high value of log K1(EDTA) for Co(III) is because it is low-spin d6

ii) The low value of log K1(EDTA) for Fe(III) is because it is high-spin d5

  iii)  The low value of log K1(EDTA) for the Sc(III) complex is becaus it has a d1 electronic configuration

iv) The low value of log K1(EDTA) for Ga(III) is because it is a d10 ion

 

Which statements are true?

  1. a) all of them b) i), ii) and iv)   c) ii) and iv)   d) i), iii), and iv)
