Question

rachel is performing an acid-base titration. she hopes to determine the concentration of an unknown acid solution to two decimal places. which is the best tool to find the volume of the base that she needs to neutralize the acid?
○ beaker
○ erlenmeyer flask
○ graduated cylinder
○ buret

Explanation:

In acid-base titration, precise volume measurement of the titrant (base) is critical. A buret allows controlled addition and accurate volume readings to two decimal places, essential for determining the endpoint. Beakers, Erlenmeyer flasks, and graduated cylinders lack the precision needed for titration.

Answer:

D. buret
