Based on the text above. Answer the followung True/False.

TRUE OR FALSE: You should make sure your volumetric flask is completely dry after rinsing it with deionized water. TRUE or FALSE: You should rinse your buret with ZnSO4 solution af ter rinsing it with deionized water. Technical Point: Volumetric Flasks and Pipets Figure A: Volumetric Flask We have learned to record volume readings on burets and graduated cylinders to one digit beyond the markings. Volumetric flasks and pipets, however, are used by filling them to a single mark. When they are filled to that mark, we know that there is a certain volume of liquid in the glassware with a certain amount of precision. For example, the 100mL volumetric flasks you will be using has a precision of 0.03mL. This means that when filled to the mark, the volume of liquid is 100.00mL0.03mL. Note that this is similar to how we round average values to reflect the uncertainty in that value based on the standard deviation of the mean. Therefore, the volume of liquid in the flask is known to 5 significant figures. Figure B: An assortment of volumetric pipets The volume of a liquid delivered from a volumetric pipet is recorded in a similar way. The pipets that we use in this course are usually marked 'TD' or to deliver. This means that after you allow your solution to drain from the pipet after filling, you do not need to blow out any remaining liquid in the tip. Like volumetric flasks, volumetric pipets have a precision of around 0.03mL. Which means the volume delivered by a 25mL pipet is 25.00mL0.03mL TRUE OR FALSE: You should make sure your volumetric flask is completely dry after rinsing it with deionized water. TRUE or FALSE: You should rinse your buret with ZnSO4 solution af ter rinsing it with deionized water
