Explanation:
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/...

  -> 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


Explanation:
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.

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.
