Q. 9.67 - 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  (B) that is $10 \% (\mathrm{m}/\mathrm{v})$sucrose will be increasing in volume.

b.  The statement of the compartment  (A) that is $8 \% (\mathrm{m}/\mathrm{v})$ albumin will be increasing in volume.

c.  The statement of the compartment  (B) that is $10 \% (\mathrm{m}/\mathrm{v})$ starch 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 $5\% (\mathrm{m}/\mathrm{v})$ sucrose solution to $10 \%$ sucrose solution. Therefore in $10 \%$ sucrose 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  $4 \% (\mathrm{m}/\mathrm{v})$albumin solution to $8\%$albumin solution. Therefore in $8\%$ 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 $0.1\%$ start  solution to starch $10 \%$ solution. Therefore in $10\%$ starch  solution water level rises.
