Beregner m.ln efter den sidste Tabel
Klornatriumge-lialten af den Klormængde, der er blevet tilovers fra Kali
og Magnesia, og adderes derpaa Salterne sammen, vil man
tinde, at Summen bliver noget lavere end de Tal. der i
Tabel l angiver Vandets samlede Saltmængde. Den
Na-triumgelialt, der erholdes ved denne Beregning bliver
nemlig for liden. da. der ikke er taget noget Hensyn til de i
mindre Mængde forekommende Syrer.
Den vigtigste af disse skulde ifølge .Hr. Tornøes
Undersøgelser være den af Baserne bundne Kulsyre. Da
Tornoe har bestemt denne Bestanddel i de samme
Vandprøver, hvori jeg senere har udført mine Analyser,
har jeg medtaget de af ham fundne Kulsyremængder ved
følgende Beregning af Søvandets Bestanddele, ved hvilken
jeg tillige har opført den Klornatriumsgebalt," der svarer
til det tiloversblevne Klor. I Overensstemmelse med. hvad
der forud er sagt, har jeg førenet den surtbundne Kulsyre
med Natron .til dobbelt kulsurt Salt. Den tiloversblevne
ringe Mængde neutraltbundne Kulsyre har jeg regnet til
Kalk. Ved Siden af den Sum, der erholdes ved Addition
af ’samtlige Bestanddele, har jeg opført den Saltgehalt. der
er fundet ved Inddampning af Søvandet efter den forud
beskrevne Methode.

Now. on computing by. the last Table the amount of
chloride of sodium from the surplus proportion’ of chlorine,
uncombined with potash and magnesia, and then adding
together the results, the total will be somewhat less than
the whole amount of salt in sea-water as given in Table 1
— and for this reason, that the proportion of sodium thus
computed is too small, no regard having been had to the
acids occurring in small quantities in sea-water.
The most important- of these, according to Mr.
Tornoe’s observations, is carbonic acid united to bases.
Mr. Tornoe having determined this constituent in the same
samples that I subsequently examined, I have taken his
carhpnic acid values for the following computation of the
constituent parts of sea-water, among -which I have, given
the amount of chloride of sodium corresponding to the
surplus of chlorine. In conformity with w-hat has been
previously .stated. I have combined the carbonic acid
occurring in bicarbonates with soda, to form bicarbonate of
soda. The small surplus of carbonic acid occurring in
bicarbonates, I have combined with lime.. Along with the total
amount found by adding together the several constituents,
I have given the proportion of salt obtained after
evaporating séa-water by the method previously described.
