three beakers, three different bases, all same concentration. Beaker A pH of 10.4, Beaker B has a pH of 13.7, and Beaker C has a pH of 8.1.?

The greater the ionization constant of a base with a certain concentration, the greater the extent of dissociation is, and thus the more concentrated hydroxide ions are produced. Moreover, the greater the concentration of hydroxide ions, the greater the pH is.

Conclusively, the greater the pH of a base with a certain concentration would be corresponding to a greater the ionization constant.

pH: Beaker B (13.7) > Beaker A (10.4) > Beaker C (8.1)
Ionization constant: 1.1 × 10² M > 3.7 × 10⁻⁵ M > 4.6 × 10⁻⁷ M

Ionization constant goes with each beaker:
Beaker A: 3.7 × 10⁻⁵ M
Beaker B: 1.1 × 10² M
Beaker C: 4.6 × 10⁻⁷ M

1.1 x 102 M ... is this 10-2? ... B
3.7 x 10-5 M ... A
4.6 x 10-7 M ... C
