200 ANAL0498: Separating Selected Metal Cations by Paper Chromatograpny 4. A student in a hurry decides to let the solvent travel only half way up the chromatographic paper in Chromatogram 2. Predict the effect of this procedural change on the resolution of the cations in the standard mixture. 5. (a) Based on your calculated

values, which cation(s) formed weakly charged complexes? (b) How does the presence of

affect the charges on the complexes? (c) If

of water, instead of

of

, were added to the acetone, how would it affect the charges on the weakly charged complexes identified in (a)? What would be the effect on their

values? How would this affect the resolution of the chromatography? (d) Explain whether or not the substitution of water for

would cause similar changes in the charges of the complexes that are strongly charged in the acetone

solvent system. A student in a hurry decides to let the solvent travel only half way up the chromatographic paper in Chromatogram 2. Predict the effect of this procedural change on the resolution of the cations in the standard mixture. (a) Based on your calculated
