Description	Eight decades ago, Peter Zuman was born when the first polarograms of aqueous %22supporting electrolytes%22 had just been recorded. Around that period, the pioneering idea of partial dissociation due to Arrhenius was unfortunately replaced by that of 'complete dissociation' and empirical mean ionic activities. Over the next decades, as the theory of electrolytes became too complicated to be meaningful, it became clear that the earlier ideas of partial dissociation and hydration were correct. Here, it is shown that solution properties of electrolytes can be explained quantitatively using simple mathematical expressions involving concentrations and volumes of ions and ion-pairs and hydration numbers. Five tables of degrees of dissociation and hydration numbers of many strong electrolytes are provided in the Appendix.

(en) Petr Zuman se narodil před osmi dekádami, když se zaznamenávaly první polarogramy „základních elektrolytů“. Přibližně v té době Arrheniova průkopnická myšlenka částečné disociace byla nahrazována teorií „úplné disociace“ a empirickými „středními iontovými aktivitami“. Po dalších dekádách, když teorie elektrolytů se stávala příliš složitou na to, aby měla praktický význam, bylo zřejmým, že dřívější pojetí částečné disociace a hydratace bylo správné. Zde je ukázáno, že vlastnosti roztoků elektrolytů mohou být kvantitativně vystiženy jednoduchými matematickými výrazy zahrnujícími koncentrace a objemy iontů a iontových párů a hydratační čísla. V příloze je podáno pět tabulek stupňů disociace a hydratačních čísel řady silných elektrolytů. (cs)
