which dye would you predict to move the fastest (and thus go furthest in a given time period) through agar? multiple choice congo red (mw = 697 g/mol) methylene blue (mw = 320 g/mol) quinoline yellow (mw = 477 g/mol) potassium permanganate (mw = 158 g/mol) cyanine (mw = 766 g/mol)

Answer

Brief Explanations:

Smaller - sized molecules (lower molecular weight) diffuse faster through agar. Among the given dyes, potassium permanganate has the lowest molecular weight (158 g/mol), so it will diffuse the fastest.

Answer:

potassium permanganate (mw = 158 g/mol)
