Q. 9.68 - An Introduction to General, Organic, and Biological Chemistry

Question

Indicate the compartment (A or B) that will increase in volume for each of the following pairs of solutions separated by a semipermeable membrane: 

Step-by-Step Solution

Answer

a. The statement of the compartment  (A) that is $20 \% (\mathrm{m}/\mathrm{v}) \mathrm{starch}$ will be increasing in volume.

b. The statement of the compartment  (A) that is $10 \% (\mathrm{m}/\mathrm{v})$albumin will be increasing in volume.

c. The statement of the compartment  (B) that is $5 \% (m/v)$sucrose will be increasing in volume.

Part (a) Step 1: Given Information

We need to describe the statement of which compartment is from A or B will show increasing volume.

Part (a) Step 2: Explanation

Water will flow from lower osmotic pressure to higher osmotic pressure and that is  $10 \%$starch solution to $20 \%$starch solution. Therefore in  $20 \%$starch solution water level rises.

Part (b) Step 1: Given Information

We need to describe the statement of which compartment is from A or B will show increasing volume. 

Part (b) Step 2: Explanation

Water will flow from lower osmotic pressure to higher osmotic pressure and that is $2\% (\mathrm{m}/\mathrm{v})$ albumin solution $10 \%$ to albumin solution. Therefore in $10 \%$ albumin solution water level rises. 

Part (c) Step 1: Given Information

We need to describe the statement of which compartment is from A or B will show increasing volume. 

Part (c) Step 2: Explanation

Water will flow from lower osmotic pressure to higher osmotic pressure and that is $0.55 \% (\mathrm{m}/\mathrm{v})$sucrose solution to $5 \%$ sucrose solution. Therefore in $5 \%$ sucrose solution water level rises.
