Among the following, the incorrect statement about colloids is:
Choose an option
Show full solutionCorrect option: C
Correct answer
CThe osmotic pressure of a collodial solution is of higher order than the true solution at the same concentration.
Step-by-step explanation
Due to the bigger size of colloidal particles the number of particles in a colloidal solution is comparatively small as compared to a true solution. Hence the values of colligative properties are of small order as compared to values shown by true solutions at same concentration.
