Which of the following statement is correct for paper chromatography?

Options

  1. AWater present in the pores of the paper forms the stationary phase.
  2. BPaper sheet forms the stationary phase.
  3. CWater present in the mobile phase gets absorbed by the paper which then forms the stationary phase.
  4. DPaper and water present in its pores together form the stationary phase.

Correct answer

A. Water present in the pores of the paper forms the stationary phase.

Step-by-step solution

The principle of paper chromatography is partition. In paper chromatography there are two phases one is the stationary phase and the other is the mobile phase. Here, water trapped in the paper acts as the stationary phase and solvent acts as the mobile phase.
