Define stepwise stability constant

WebA cumulative constant can always be expressed as the product of stepwise constants. Conversely, any stepwise constant can be expressed as a quotient of two or more overall constants. There is no agreed notation for stepwise constants, though a symbol such as KL ML is sometimes found in the literature. It is best always to define each stability ... WebHigher the value of stability constant for a complex ion, the greater will be its stability. Inverse if the formation onstant (K f = 1/k) is called dissociation constant (K d) or instability constant of the complex.
