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?

A buret is designed to dispense and measure precise, adjustable volumes of liquid, making it the best tool for tracking how much base is added during a titration. Its graduations and stopcock allow Rachel to add the base carefully until the acid is neutralized. A graduated cylinder is less precise, while beakers and Erlenmeyer flasks are not designed for accurate volume delivery.
