Question
Chapter 9, Problem 2Q
Interpretation Introduction
Interpretation:
The advantages of the fluted filter paper in the gravity filtration should be determined.
Concept introduction:
Filtration is a physical process that is used to separate solid matter from a liquid by adding a filter medium through which only the liquid can pass. Gravity filtration is one of the methods of filtration of impurities from solutions by the use of gravity to pull liquid through a filter.

why is a fractionating column better able to separate liquids?
The volume of the solution that can be measured with 5-10 microliter pipette and 2-20 microliter pipette is 0.005-0.01 mL and 0.002 mL-0.02 mL.
The volume of the solution that can be measured with 20-200 microliter is 0.02-0.2 mL. The volume 1 mL of solution is measured with 100-100 microliter which has capacity of 0.1 mL to 1 mL.
What would the display read for 0.10 mL, 0.20mL, 0.40mL, 0.60 mL, 1.0 mL read when using the micropipettes mentioned above
