A formation constant, kf, also sometimes known as a stability constant or association constant is used to describe the formation of a complex ion from its central ion and its attached ligands. the equilibrium constant expression for kf follows the same general form as any other typical equilibrium constant expression, with products over the.
Solved O Ref Ka Kd Ke Kf Ke Kf Kd Ke Ke Kh Kh 0 Kf Kh Kh Affinity in chemistry is the tendency of dissimilar chemical species to form chemical compounds. dissociation constant (kd ) is the rate constant of dissociation at equilibrium, defined as the ratio koff kon (where koff and kon are the rate constants of association of the drug off and on to the receptor). Example: i have a solution that contains 0.50 m of compound a and 0.20 m of compound b. if i start with no c at all and let the reaction run for a while, what will the equilibrium concentrations of each compound be? answer: plug it all into the equilibrium expression. here’s how: initially, you’ve got 0.50 m of compound a. Now set up the equation: kf = [ag (nh3)2 ] [ag ] [nh3 ]^2. plug in 0.98 for nh3, x for [ag ], and 0.01 for ag (nh3)2 . agno3 pretty much completely dissolves, leaving you with 0.01m ag ions. now, that ag reacts with nh3 to form the complex ag (nh3)2 . ag 2nh3 <=> ag (nh3)2 . but you need 2 nh3 for every 1 ag . Complex ions typically exist in complex equilibrium involving its central metal ion and the ligands. a metal ion in solution does not exist in isolation, but in combination with ligands (such as solvent molecules or simple ions) or chelating groups, giving rise to complex ions or coordination compounds.
