Q: <\/strong>A and B chambers, containing solutions\u00a0 are separated by a semi-permeable membrane.<\/p>\n

\"\"<\/p>\n

(a) <\/strong>Solution of which chamber has a lower water potential?<\/p>\n

Ans:<\/strong> B- chamber.<\/p>\n

Reason:<\/strong> B-chamber contains more solute than that of A-chamber, therefore, it contains less free water molecule than that of the adjacent chamber. Thus, it has lower water potential than chamber A.<\/p>\n

(b) <\/strong>Solution of which chamber has a lower solute potential?<\/p>\n

Ans:<\/strong> B- chamber.<\/p>\n

Reason:<\/strong> Refer NCERT page no 179, “the more the solute molecules, the lower is the solute potential<\/em>“. Therefore, B-chamber contains more solute molecules, hence, it has lower solute potential than chamber A.<\/p>\n

(c) <\/strong>In which direction will osmosis occur?<\/p>\n

Ans:<\/strong>\u00a0 From A to B- chamber.<\/p>\n

Reason:<\/strong> Water potential means, “tendency of water to move from higher solvent concentration than that of lower solvent concentration”. <\/em>Chamber A contains less solute than that of B-chamber, therefore, A contains more free water (solvent) molecule than that of the B- chamber.<\/p>\n

(d) <\/strong>Which solution has a higher solute potential?<\/p>\n

Ans:<\/strong> A- chamber solution.<\/p>\n

Reason:<\/strong> Refer NCERT page no 179, “the more the solute molecules, the lower is the solute potential<\/em>“. It means, if, the number of solute molecule is less than that solution have more solute potential. Therefore, A-chamber contains less solute molecules, hence, it has more solute potential than chamber B.<\/p>\n

(e) <\/b>At equilibrium which chamber will have a lower solute potential?<\/p>\n

Ans:<\/strong> The two chambers will have nearly the same water potential.<\/p>\n

Reason:<\/strong> Refer NCERT page no 180, “at equilibrium the two chambers should have nearly the same water potential”.\u00a0<\/em><\/p>\n

(f) <\/b>If one chamber has a water potential of -2000 kPa, and the other -1000 kPa, which is the chamber that has the higher water potential?<\/p>\n

Ans:<\/strong> -1000 kPa<\/p>\n

Reason:<\/strong> Refer NCERT page no 179, “the water potential of pure water at standard temperatures, which is not under any pressure, is taken to be zero.” <\/em>Hence, more negative value means less water potential.<\/em><\/p>\n

(g) <\/b>What will be the direction of the movement of water when two solutions with water potential 0.2 MPa and water potential 0.1 MPa are separated by a selectively permeable membrane?<\/p>\n

Ans:<\/strong> From water potential 0.2MPa to 0.1 MPa<\/p>\n

Reason:<\/strong> 0.2 > 0.1. Movement of water takes place from higher water potential to lower water potential.<\/p>\n","protected":false},"excerpt":{"rendered":"
