Which of the following statements about colloids is false?
Which of the following statements about colloids is false?
Options
- AWhen silver nitrate solution is added to potassium iodide solution a negatively charged colloidal solution is formed.
- BFreezing point of colloidal solution is lower than true solution at same concentration of a solute.
- CColloidal particles can pass through ordinary filter paper.
- DWhen excess of electrolyte is added to colloidal solution, colloidal particle will be precipitated.
Correct answer
B. Freezing point of colloidal solution is lower than true solution at same concentration of a solute.
Step-by-step solution
Freezing point of colloidal solution is same as that of true solution at same concentration of a solute. The depression in freezing point is colloidal property and depends on the number of solute particles. It is independent of size or shape of solute particles.
