Question : 11 of 16

Marks: +1, -0

Assertion (A):

0.1\ \mathrm{M}

solution of

\mathrm{KCl}

has greater osmotic pressure than

0.1\ \mathrm{M}

solution of glucose at same temperature.

Reason ( $R)$ : In solution,

\mathrm{KCl}

dissociates to produce more number of particles.

Both Assertion (A) and Reason (R) are correct statements, and Reason (R) is the correct explanation of the Assertion (A).
Both Assertion (A) and Reason (R) are correct statements, but Reason (R) is not the correct explanation of the Assertion (A).
Assertion (A) is correct, but Reason (R) is wrong statement.
