What physical property separates substances in column chromatography( and chromatography in general)?
Homework Answers
In chromatography the substances are separated based on the differences in the absorption of compounds to the absorbent.
Different compounds are absorbed at different column as the rate of absorption is different
And the components are separated

Question 1 (1 point) Saved Chromatography is a technique that separates substances in a mixture based on the interactions of the mixture components with a mobile phase and a stationary phase. True False Question 2 (1 point) Saved The mobile phase carries substances along at a rate that is dependent on the attraction of the substance to the stationary phase. True False Question 3 (1 point) Use 10 mL of 10% isopropanol followed by 10 mL of distilled water to...

What is the main purpose of running a column chromatography? Similar to TLC. column chromatography is based on analytes being partitioned between a stationary phase (not moving) and a mobile phase (moving). What is most commonly used as stationary phase in a column? Is this material polar or non-polar? In this experiment, you will use different solvents to run column chromatography separation of different pigments extracted from spinach leaves. These solvents are a mixture of acetone and hexanes. (a) What...
