I have a mixture of E. coli, L. Broth, ampicillin, and phenol red. I want to measure the concentration of E. coliusing a spectrophotometer. What do I blank the spec with? (Select all that apply.)
A) Ampicillin
B) E. coli
C) Ethanol
D) L. Broth
E) NaCl ions
F) Penicillin
G) phenol red
H) Water
Also please include just a short explanation, thank you!!
Homework Answers
Answer:
D) L. Broth
Since the L broth (the media in which E Coli grows) also has
residual absorption it is used as blank.

Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...

Assuming no heat was lost from the system, calculate the mass m...
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...
