The term infinite dilution refers for:

(a) At infinite dilution of the weak electrolyte dissociates like a strong electrolyte. This will result in the complete ionization of electrolytes. Hence, the degree of dissociation will be 1 i.e. α→1.

(b) Therefore, the solution will be 100% ionized.
(c) At the infinite dilution, the ions in an electrolytic solution are placed far apart from each other which nullifies the interionic effect and makes it zero.
(d) This will result in the equivalent conductance of an electrolyte solution to become constant
