How and why did Rf values differ for each solvent system?
The Rf value is calculated by dividing the distance a compound travels by the distance the solvent front travels. Different solvent systems have varying polarities which can affect the interaction between the compound and the stationary phase, resulting in different distances traveled by the compound. Therefore, the Rf values differ for each solvent system due to the varying affinities between the compound and the stationary phase in different solvent environments.
Would RF values of amino acid you use in paper chromatography be the same if you use another solvent system?
No, RF values depend on the specific solvent system used in the chromatography process. Changing the solvent system can alter the interactions between the amino acids and the stationary phase, resulting in different RF values. It is important to optimize the solvent system to achieve accurate and reproducible results.
How would you expect Rf values to change if you went from hexane-ethyl acetate solvent system to ethyl acetate only?
If you switch from a hexane-ethyl acetate solvent system to ethyl acetate only, you would expect the Rf values to decrease. Ethyl acetate is a more polar solvent than hexane, so compounds will interact more with the solvent and have shorter distances of travel on the TLC plate, resulting in lower Rf values.
Why are the relative values of the individual exchangeable bases as they are in the topsoil and subsoil and, if the horizons differ, why?
The soil profile is a vertical section of the soil that depicts all of its horizons.
What are the significance of values?
Rf Values determine the solubility of a substance with respect to a certain solvent.
What is relative conductivity?
Relative conductivity refers to the ability of a material to conduct electricity compared to a standard material. It is commonly used to compare the conductivity of different materials based on their relative values. Materials with higher relative conductivity values exhibit better electrical conductivity than materials with lower relative conductivity values.
Which chart compares relative values of different categories to the whole?
The Doughnut chart and pie chart, compares relative values of different categories to the whole
Do men and women differ in values?
yes
Properties of values according to Tomas Andres?
According to Tomas Andres properties of values include: value is relative, value is subjective, value is objective, value is bipolar and value is hierarchical. His- Understanding Filipino Values is a book that relates the Filipino value system.
