Among the following, the false statement is:

Options

  1. ALatex is a colloidal solution of rubber particles which are positively charged
  2. BTyndall effect can be used to distinguish between a colloidal solution and a true solution.
  3. CIt is possible to cause artificial rain by throwing electrified sand carrying charge opposite to the one on cl
  4. DLyophilic sols can be coagulated by adding an electrolyte.

Correct answer

A. Latex is a colloidal solution of rubber particles which are positively charged

Step-by-step solution

Latex is a colloidal solution of rubber particles which are negatively charged not positively charged.
