What is electrodialysis?

Text Solution

AI Generated Solution

**Step-by-Step Solution:** 1. **Definition of Electrodialysis**: Electrodialysis is a method used for the purification of colloidal solutions that contain ionic impurities. 2. **Setup for Electrodialysis**: To perform electrodialysis, an impure colloidal solution is placed in a parchment bag. This bag acts as a semi-permeable membrane. 3. **Application of Electric Field**: An electric field is applied across the parchment bag. This electric field is crucial as it facilitates the movement of charged particles. ...
