In paper chromatography,

A

Moving phase is liquid and stationary phase is solid

B

Moving phase is liquid and stationary phase is liquid

C

Moving phase is solid and stationary phase is solid

D

Moving phase is solid and stationary phase is solid

Text Solution

Verified by Experts

The correct Answer is:
B
The elutent is a liquid (Moving phase )and also stationary phase is liquid.
Paper chromatography is a liquid-liquid partition chromatography on which the water adsobed or chemically bound to cellulose of paper acts as the stationary phase while the mobile phase is another liqiud which is a mixture of two or three solvents (water is one of these components )

  • A substance is analyzed by paper chromatography, giving the chromatogram shown. What is the R_(f) value of the substance represented by the spot at 8.0 cm?

    A
    `0.80`
    B
    `0.75`
    C
    `0.67`
    D
    `0.60`

  • Assertion (A) : Compounds of a mixture of red and blue inks can be separated by distributing the compounds between stationary and mobile phases in paper chromatography. Reason (R) : The coloured components of inks migrate at different rates because paper selectively retains different components according to the difference in their partition between the two phases.

    A
    Both A and R are correct and R is the correct explanation of A.
    B
    Both A and R are correct but R is not the correct explanation of A.
    C
    Both A and R are not correct
    D
    A is not correct but R is correct

    Assertion (A) : Components of a mixture of red and blue inks can be separated by disturbing the component between stationary and mobile phases in paper chromatography. Reason (R) : The coloured components of inks migrate at different rates because paper selectively retains different components according to the difference in their partition between the two phases.
