Sullivan Velazquez · Answer 1

it would be same

because even if the length of the strip is increased the solvent front and the chromatagram will be same if u use the same mixture

Kelsie Andersen · Answer 2

It would be the same

Explanation:

RF

It is the ratio of the distance moved by a compound at the mobile phase in contrast to the distance moved via the front of the mobile phase. It is usually more than or equivalent to zero, and not up to or equivalent to one.

The Rf values is going to be the same due to the fact that the Rf is a ratio and the ratio will remain the same irrespective of the length of the strip being used.
