\(\mathrm{X}_{3} Y_{2}(\mathrm{i}=5)\) when reacted with \(\mathrm{A}_{2} \mathrm{~B}_{2}(\mathrm{i}=4)\) in aqueous solution gives brown colour. These are separated by a semi permeable membrane AB as shown. Due to osmosis there is
1 Brown colour formation in side X
2 Brown colour formation is side Y
3 Formation of brown colour in both of the sides X and Y
4 No brown colour formation
Explanation:
No colour formation on any side as during osmosis, only solvent particles move through SPM not the solute particles.

Assertion : If blood cells are placed in pure water, they swell and burst. Reason : Due to osmosis, the movement of water molecules into the cell, dilutes the salt content.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Osmosis involves the movement of solvent from a region of its higher concentration to lower concentration. The concentration of water been high in pure water, water enters the blood cell from outside and this bursts the cell. So option (2) is correct.
