Answer:
3.2M HCl Solution
Explanation:
Molarity = moles of solute / volume of solution expressed in liters
moles of solute = 0.80 moles HCl
volume of solution = 250 ml = 0.250 Liter
Molarity (M) = 0.80 moles HCl / 0.250 Liters = 3.2M HCl Solution
A cation-exchange column is a type of chromatography that separates substances according to their charges. The cation-exchange column in particular has a negatively charged resin that will attract positively charged ions.
Applying this principle with amino acids, we can say, for example that the negatively charged ones (e.g., aspartate and glutamate) will elute first compared to the positively charged ones (e.g., lysine, arginine, and histidine), which will elute last.
