A short fundamental description of the equilibrum model for a closed water system having been made, this model is extended for proton reactions and redox reactions. By this extension we come to the definition of the activity pH, the redoxpotential Eh and the corresponding Eh-pH diagram. A rough description of the open thermodynamic system has been given and illustrated by two examples.","AbstractOtherLang":"Voor zover mogelijk is een duidelijke scheiding aangebracht tussen theoretische evenwichtsmodellen inclusief Eh en pH en de werkelijke open-waterige systemen. Na een korte fundamentele afleiding en beschrijving van het evenwichtsmodel voor een gesloten waterig systeem, wordt dit model uitgebreid voor zuur-base en redoxreacties. Eh-pH diagrammen zijn daarmee ingevoerd. Het begrip open thermodynamisch systeem wordt ruwweg omschreven met als voorbeelden de biosfeer en een recent laagje marien sediment.","BibLvlCode":"MS","StandardTitle":"Evenwichtsmodel en Eh-pH-meting in recent estuarien sediment: Een literatuuronderzoek","OrigTitleLangCode":"nl","OrigTitleLangCodeExtended":"dut","OrigTitleLangID":41,"DateLastModified":{"date":"2025-07-25 01:33:49.256478","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":null,"MonPub":1977,"DateUpdate":"2025-07-18","DateCreate":"2001-07-10","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1},"refs":null,"anarec":null,"monrec":{"MonID":13121,"ISBN":null,"PubliDate":1977,"IssueDate":null,"Volume":"1977","Issue":"2","Pagination":"64","Place":"Texel","Edition":null,"BRefXtra":null,"BRefXtraRR":null,"SerID":5036,"SerRR":"Interne verslagen Nederlands Instituut voor Onderzoek der Zee.
