c. Quantitatively transferring dissolved solids from a beaker by pouring washings into the final container d. Using cold distilled water to dilute a solution to mark so it does not get hot e. Using a volumetric pipette when applicable to get the most accurate aliquot volume f. After diluting to around 90mL before the mark, transfer the solution into a beaker to cool down more efficiently. g. Storing everything in plastic containers as plastic is more inert than glass for most chemicals Note: Just answer, no explanation needed. Thanks
