What is the common nature of the charge on colloidal particles?

Options

  1. APositive
  2. BNegative
  3. CNeutral
  4. DVariable

Correct answer

B. Negative

Step-by-step solution

The paragraph states that colloidal particles always carry an electric charge, and the nature of this charge is the same on all particles in a given colloidal solution. It can be either positive or negative, but the examples provided suggest a common nature of negative charge.
