For Polymers lab. In what region of the two-phase system was the
Nylon-6,10 polymer formed after the sebacoyl chloride/cyclohexane
and 1,6-hexanediamine/sodium hydroxide solutions were mixed?
Why?
What are the disadvantages of polymers? What is an electrical
property of a polymer and is there any exception to that electrical
property? if so, what is it?
Mixtures of two different polymers belong to the class of
polymer blends.
a) Explain why a two-phase system can form when mixing two
different polymers. Give two examples of morphology types that may
occur (sketch).
b) Show by example how the morphology of a blend influences the
macroscopic properties of the blend.
this question from HPLC lab :
b. What are ways, other than changing the mobile phase
compositions, to change the total retention or selectivity of the
system towards the compounds? other than changing the mobile phase
compositions (Temperature, sorbent, pH, etc...?)

Pre-Lab Questions:
What color will endospore negative bacteria be after endospore
staining? What color will mycobacteria bacteria after mycolic acid
staining? (see the endospore and acid fast tables)
What species of bacteria are we going to use to look at
endospores and what species will we use for mycolic acid
staining?
Why do we briefly heat our bacteria on the slide before
staining?
