Question

How would you determine the order of dissociation for a polyprotic acid with Ka values of 4.5 x 10^-2, 1.8 x 10^-4, and 3.2 x 10^-6?

Accepted Answer

The first dissociation occurs with Ka = 4.5 x 10^-2, followed by 1.8 x 10^-4, then 3.2 x 10^-6.

Answer

All dissociations occur simultaneously.

Answer

The first dissociation occurs with Ka = 3.2 x 10^-6, followed by 1.8 x 10^-4, then 4.5 x 10^-2.

Answer

The order cannot be determined from Ka values.
