Question
Chapter 3.2, Problem 10E
Interpretation Introduction
Interpretation:Consequences of use of no preheated Pasteur filter and filter-tip pipets before filtration should be determined.
Concept introduction:Pasteur pipet consists of glass tube that is designed in such way that its one end forms tip through which liquid is allowed to enter with help of latex suction bulb. Pasteur filter-tip is modified version of Pasteur pipet; it is useful to transfer liquids with volatile components.

4. What are the conditions for a successful gravimetric analysis.
5. Define nucleation. What conditions are important for this stage.
Aside from TLC and paper chromatography, what are the other types of chromatography. Discuss their principles, applications and limitations.
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?
