Wich of the following is NOT true about the blank for the experiment, 'Analysis of a Complex Iron Salt'?

Question

A. A blank is composed of the solvent used to dissolve the analyte. For this experiment, the solvent is a combination of sulfuric acid, phosphoric acid, and water.
B. The volume required to titrate the blank is subtracted from the volume used to titrate the analyte solution to give the "corrected volume".
C. A blank is titrated to correct for any reactive impurities in the solvent. For this experiment, the impurities would be reducing agents that would react with KMnO4 (mimicking the behavior of C2O42– ).
D. The blank for this experiment must have 100 % transmittance if placed in a spectrometer (Spec 20).
E. All of these are true.

Answer 1

First off, yes they misspelled "wich"

second. the answer is NOT EEEEE!

third, the answer IS D!!!

if the date on this is old, and youre from a future webworks, make sure to read the answer and not just the letter because sometimes they mix up the choices to screw with your head.

goodluck!

Answer 2

YEA!!!!!!!! I GOT IT RIGHT
ANSWER IS The blank for this experiment must have 100 % transmittance if placed in a spectrometer (Spec 20).

Answer 3

I am from de futurez. Mr. anteater speaks the truth. trust hiiiiim......

Answer 4

no, the answer if F

Answer 5

The answer is definitely "The blank for this experiment must have 100 % transmittance if placed in a spectrometer (Spec 20)."

Answer 6

guys the answer is NOT "The blank for this experiment must have 100 % transmittance if placed in a spectrometer (Spec 20)." Sapling marked me wrong :(
Apparently, the answer is A "A blank is composed of the solvent used to dissolve the analyte. For this experiment, the solvent is a combination of sulfuric acid, phosphoric acid, and water."
