(0.05 M CuSO ₄ ) when treated with (0.01 M K ₂ Cr ₂ O ₇ ) gives green colour solution of ( Cu ₂ Cr ₂ O ₇ ). The two solutions are separated as shown below : [SPM : Semi Permeable Membrane] Due to osmosis :

Options

  1. AMolarity of ( CuSO ₄ ) solution is lowered.
  2. BMolarity of ( K ₂ Cr ₂ O ₇ ) solution is lowered.
  3. CGreen colour formation observed on side Y.
  4. DGreen colour formation observed on side X.

Correct answer

A. Molarity of ( CuSO ₄ ) solution is lowered.

Step-by-step solution

Only solvent Molecules are allowed to pass through the SPM.
