Which statement about reflux setups is NOT correct? The boiling temperature of the solvent overlaps with the optimal temperature of the reaction. The temperature of water entering the condenser must be the same as the reaction temperature. The reaction typically takes place inside a round-bottom flask. Reflux allows the solvent volume to stay the same throughout the reaction.

In recrystallization, fluted filter paper is used instead of a regular cone because it minimizes its contact with the glass funnel. Why is this important?
Volumetric pipettes are designed to deliver a precise amount of liquid, but only if you a. submerge the end of the pipette into a solution you are delivering. b. allow the pipette to drain freely, and leave any residual solution in the pipette. c. hold the pipette at a 45 degree angle and ensure that all the liquid is delivered.
