Fill in the blanks by choosing the appropriate word/words from those given in the brackets.(dialysis, peptization , dispersed phase , dispersion medium , electrophoresis , electro-osmosis , coagulation , coagulates, emulsion , gel , gold number , Tyndall effect , protective colloids , electrodialysis)
The movement of dispersion medium under the influence of an electric field is called.....

Explanation

To solve the question, we need to fill in the blank with the appropriate term that describes the movement of the dispersion medium under the influence of an electric field.

### Step-by-Step Solution:

1. **Understanding the Context**: The question is about the behavior of a colloidal solution when an electric field is applied. In colloidal chemistry, the dispersion medium refers to the solvent or phase in which the colloidal particles are dispersed.

2. **Identifying Key Terms**: The options provided include terms related to colloidal systems and their behavior under various conditions. We need to focus on the term that specifically relates to the movement of the dispersion medium when an electric field is applied.
