WebMar 9, 2024 · Calculating RF RF= Distance moved by compound / Distance moved by solvent For the purple spot in figure 3b (the textbook diagram), the RFis 0.8. For the same spot in figure 3a (typical student results), what is the distance moved by the spot? Where would you draw the line? There will be a very large error in any value calculated. WebThe RF value formula is expressed as: RF value = DSU / DSV. Where DSU is the distance traveled by the solute and DSV is the distance traveled by the solvent. The RF value is …
WebThe R f value is calculated as follows: If the R f value of one of the components of the mixture equals the R f value of one of the standard reference materials then that component is know to be that reference material. Note that because the solvent always travels at least as far as the highest dye, the R f value is always between 0 and 1. Web10. Calculate the Rf values for each pigment and record the values in Data Table 1 (column E) using the following formula Rf = distance pigment travels distance the solvent front travels 11. Use Appendix B to determine the name of each pigment and record the name in Data Table 1 (column F). Day Two
