what is the meaning of dissociation constant?

Expert Answer:

a dissociation constant is a specific type of equilibrium constant that measures the propensity of a larger object to separate (dissociate) reversibly into smaller components,

The dissociation constant is usually denoted Kd and is the inverse of the affinity constant. In the special case of salts, the dissociation constant can also be called an ionization constant.

For a general reaction

in which a complex AxBy breaks down into x A subunits and y B subunits, the dissociation constant is defined

where [A], [B], and [AxBy] are the concentrations of A, B, and the complex AxBy, respectively.
