Suppose you were required to make a solution by diluting 20.0 mL of an aqueous solution to a final volume of 750 mL.
Describe, in as much detail as possible, the entire dilution process from beginning to end as described in this lab. Points awarded will be proportional to the level of detail you provide. How the two solutions are properly mixed together? What is the role of the meniscus in this process?
