Discussion

Herbmione Granger May 23, 2017:
@Bjoern Thanks for the supporting material. I submitted "sample" as an answer, because even "analyte" has too much technical baggage.
Björn Vrooman May 23, 2017:
... Agree with herbalchemist. There's no need to make this more complicated than it already is. This is like probably all you need:

http://www.chemguide.co.uk/physical/acidbaseeqia/phcurves.ht...
https://www.creative-chemistry.org.uk/alevel/module1/documen...

Not one of them mentions "receiver."

The question can be found in similar form (including "Vorlage") on:
https://de.wikibooks.org/wiki/Praktikum_Anorganische_Chemie/...

See part in bold:
"Aus dem Verbrauch an Maßlösung und der eingesetzten Stoffmenge an Natriumcarbonat kann die Konzentration der Salzsäurelösung bestimmt werden."
Herbmione Granger May 23, 2017:
Not a Distillation "Vorlage" has many uses in the field of Chemistry (http://www.chemie.de/search/p3/?q=vorlage&lastsource=lexikon... The combination of Vorlage/Verbrauch should be taken into account. In this context, it may simply mean "sample" (https://link.springer.com/article/10.1007/BF00423627) or some sort of starting point.
Edith Kelly May 23, 2017:
Elif sorry, I did not see JackMark's discussion entry but it's the solution for sure
Elif Baykara Narbay May 23, 2017:
EdithK I wanted to provide an explanation regarding JackMark's question mark. Or did I misunderstood completely?
Edith Kelly May 23, 2017:
Elif of course it is the receiving solution simply referred to as receiver, it's not a flask. It did not occur to me that receiver in this connection could be misinterpreted.
Elif Baykara Narbay May 23, 2017:
Both It can refer to both the receiver flask (distillation) and the receiver solution, depending on the context. Considering a titration procedure, it is most likely a solution. You can use "receiver" only just to be on the safe side, but I believe that it is the solution.
Jacek Kloskowski May 23, 2017:
Not sure if it fits:

Routledge German Dictionary of Chemistry and Chemical Technology:

Vorlage f [distillate, distillation, still] receiver, (lab also) receiving flask

Sample

Although I don't think that "analyte" would cause mayhem, I think that it would cause some discord. An analyte is a chemical/mixture of interest. In an acid-base titration the analyte is the thing in the beaker being dripped upon, in this case HCl. However, the HCl is a primary standard (Urtitersubstanz) whose titer is known and the investigator is looking for the titer of the NaOH, which makes it, not HCl, the chemical/mixture of interest. I am proposing that "sample" is a better answer than "analyte" considering the context. (Thanks, Bjoern, for making me take a closer look at the reference https://de.wikibooks.org/wiki/Praktikum_Anorganische_Chemie/...

It seems that this is connected to an earlier question about "Titrationsvorschriften." http://www.proz.com/kudoz/german_to_english/chemistry_chem_s...

Peer comment(s):
agree Björn Vrooman : I'd even go so far as to suggest "solution" only; yes, there are two, but I don't see how you can confuse them. Asker's text is from a website on teaching materials; you shouldn't make it more complicated than the links I posted in the d-box.

Right about "solution" not being indicative enough. It wouldn't be used as a header unless a list of solutions followed. We are certainly interested in the neutralization of the HCl given. The ultimate goal is to determine the quality of the NaOH.

in this connection.

See also, though in a different connection but same principle.

good morning and thanks.
disagree Róbert Hanczkó, Ph.D. : Buchi is a Swiss company - "receiver" solution might be a bad choice of words. "Analyte solution" generates appr. twice as many hits...

thanks, I suppose you are a chemist to be so sure. Well, I actually do not need the Net to be sure. I would not go for analyte in such a general context.

Analyte

Titration, also known as titrimetry,[1] is a common laboratory method of quantitative chemical analysis that is used to determine the unknown concentration of an identified analyte. Since volume measurements play a key role in titration, it is also known as volumetric analysis. A reagent, called the titrant or titrator[2] is prepared as a standard solution. A known concentration and volume of titrant reacts with a solution of analyte or titrand[3] to determine concentration. The volume of titrant reacted is called titration volume.

https://en.wikipedia.org/wiki/Titration

Titration is a common laboratory method of qualitative chemical analysis that can be used to determine the unknown concentration of a solution (analyte). The basis of this process is the reaction between the analyte and a solution of unknown concentration (standard solution). The analyte is taken in a conical flask using a pipette and the solution of known concentration is take in a calibrated burette (titrant).

https://en.wikipedia.org/wiki/Titration

Bei einer Titration (Maßanalyse) wird ein Stoff aus der Bürette (der "Titrator") einem Stoff in der Vorlage
(der "Titrand"), in der Regel ein Erlenmeyerkolben, zugetropft. Der "Endpunkt" der Reaktion liegt vor, wenn
"äquivalente Stoffmengen" miteinander regiert haben.
