Which of the following colloids cannot be formed by direct mixing? Correct Answer Lyophobic colloids

Lyophobic colloids such as metal solutions like gold and silver solution, sulphur solution and blood cannot be prepared directly by mixing. These are prepared by special methods and are irreversible in nature. Once the dispersed phase and medium are separated it is not possible to get the solution by remixing the two phases.
