In titration, do you put the solution of unknown concentration in the conical flask or the burette?

Question

Please answer ONLY if you know and the reason if there is 1...thx

Answer 1

It could be either way. What usually determines which solution goes in the buret is the nature of the indicator. For example, in an acid/base titration where phenolphtalein is the indicator, you would want the acid in the flask and the base in the buret. This is because the indicator is pink in base...for this particular titration to work best, you would want the indicator to go from colorless to pink, not pink to colorless. It wouldn't matter which solution was of an unknown concentration.

EDIT: Someone who responded after me states (incorrectly) that the known concentration has to go in the buret since the buret is graduated and you want to precisely measure how much of the known solution is added. However, the volume of the solution initially placed in the flask can ALSO be measured very precisely by using glassware such as a volumetric pipet.

Answer 2

The unknown concentration is placed in the conical flask. The one that is placed in the burette is the solution with known concentration. You see, the burette is graduated. It's only logical to put the known concentration there so that you will be able to do calculations. Otherwise, it won't make any sense.

Answer 3

Conical Flask...
Because in neutralization reaction we will be measuring the pH of the solution over and over again till the pH reach the neutral point (pH 7)...
