question_answer 43)

  Which of the following complexes formed by ions is most stable? (a), log k = 6 (b) , log k = 27.3 (c)   ,   log K=15.4 (d) , log K = 8.9

Answer:

                (b) Greater the value of log K, greater will be stability of complex compound formed. For reaction,                        For this reaction, log K has highest value among the given four reactions. Hence, K will            also be higher among these four. i.e., stability of the complexes will be highest among  these four complexes.
