A student investigated the sacrificial protection of iron by wrapping four identical iron bolts with different metal wires (zinc, copper, magnesium, and tin). They placed each bolt into a separate boiling tube and added 25 cm325\text{ cm}^325 cm3 of sodium chloride solution to each tube.
State why a measuring cylinder is adequate, rather than a volumetric pipette, to measure the 25 cm325\text{ cm}^325 cm3 of sodium chloride solution.
