Similar to the case for polyprotic acids, note the ionization constants decrease with ionization step.

From Textbooks • Feb. 14, 2019

This stepwise ionization process occurs for all polyprotic acids.

From Textbooks • Feb. 14, 2019

Likewise, equilibrium calculations involving polyprotic bases follow the same approaches as those for polyprotic acids.

From Textbooks • Feb. 14, 2019

This is a general characteristic of polyprotic acids and successive ionization constants often differ by a factor of about 105 to 106.

From Textbooks • Feb. 14, 2019

The ionization constants for polyprotic acids decrease with each subsequent step; these decreases typically are large enough to permit simple equilibrium calculations that treat each step separately.
