C. Retention factor
D. Total porosity
Answer:C
Which of the following is defined as the ratio of moles of solute in stationary phase to the moles of solute in mobile phase?
A. Distribution constant B. Volumetric phase ratio C. Retention factor D. Total porosity
Explanation: Retention factor is defined as the ratio of moles of solute in stationary phase to the moles of solute in mobile phase. It is used for determining the migration rates of solutes in the column.
