Question

question 8 12.5 pts if a sample tested had an r_f value of zero, what does this indicate about the components attraction to the mobile phase? it was not attracted to the mobile phase. it was highly attracted to the mobile phase. it was slightly attracted to the mobile phase.

Explanation:

In chromatography, the \( R_f \) value is calculated as \( R_f=\frac{\text{distance traveled by component}}{\text{distance traveled by mobile phase}} \). If \( R_f = 0 \), the component did not move from the origin, meaning it had no attraction to the mobile phase (since it didn't travel with the mobile phase at all).

Answer:

It was not attracted to the mobile phase.
