An analyst performs an acid-base titration to determine the exact concentration of ethanoic acid in a commercial vinegar sample. Before beginning the titration, a precise volume of exactly 25.0 cm3 of the vinegar must be measured out and transferred into a clean conical flask.
Figure 1 shows three pieces of laboratory glassware.
Identify the letter, A, B, or C, of the piece of apparatus shown in Figure 1 that must be used to measure and transfer this precise 25.0 cm3 volume of vinegar.
