Options

  1. Athe dispersed phase migrate in an electric field.
  2. Bthe dispersed phase does not migrate in an electric field.
  3. Cthe dispersed phase has pH equal to 7 .
  4. Dthe dispersed phase has pH equal to zero.

Correct answer

B. the dispersed phase does not migrate in an electric field.

Step-by-step solution
