(0.05 \mathrm{M} \mathrm{CuSO}_4) when treated with (0.01 \mathrm{M} \mathrm{K}_2 \mathrm{Cr}_2 \mathrm{O}_7) gives green colour solution of (\mathrm{Cu}_2 \mathrm{Cr}_2 \mathrm{O}_7). The two solutions are separated as shown below : [SPM : Semi Permeable Membrane] (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
Due to osmosis :

Options

  1. AMolarity of (\mathrm{CuSO}_4) solution is lowered.
  2. BMolarity of (\mathrm{K}_2 \mathrm{Cr}_2 \mathrm{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 (\mathrm{CuSO}_4) solution is lowered.

Step-by-step solution

Only solvent Molecules are allowed to pass through the SPM. (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
