Chemistry Question on Surface Chemistry
All colloidal dispersions have
A
very high osmotic pressure
B
low osmotic pressure
C
no osmotic pressure
D
high osmotic pressure
Answer
low osmotic pressure
Explanation
Solution
Colloidal particles are bigger aggregates . Thus, the number of particles in the colloidal solution is comparatively small as compared to true solution. Hence, the values of colligative properties (e.g., osmotic pressure) are of small order as compared to values shown by true solutions at the same concentrations.
