However at p. 147 it's written that a solution with a pH of 10 is a strong alkali. So either the correlation of pH with conductivity is incorrect or the statement that ammonia solution with a pH of 11.1 is a weak Alkali is wrong.

Ein Weg, herauszufinden, wie stark eine Base ist, geht über die protochemische Spannungsreihe, in der die pKb- und pKs-Werte einiger Säure-Base-Paare aufgelistet sind, wobei die pKb-Werte die Basenstärke bezeichnen und die pKs-Werte die Säurestärke bezeichnen. Die pKs- und pKb-Werte geben an, inwieweit eine Base bei der Gleichgewichtsreaktion mit Wasser ionisiert vorliegt. Dabei gilt: Je größer der Wert desto schwächer ist die Säure/Base.
