Which of the following methods is used to purify colloidal solutions? (2020)

Step 1: Understand what a colloidal solution is. It is a mixture where tiny particles are dispersed in a liquid.
Step 2: Know that colloidal particles are larger than regular molecules but smaller than what can be seen with the naked eye.
Step 3: Learn about dialysis, which is a method used to separate substances in a solution.
Step 4: Recognize that dialysis uses a semi-permeable membrane, which allows certain substances to pass through while blocking others.
Step 5: In the case of colloidal solutions, the semi-permeable membrane lets the solvent and small solutes pass through but keeps the larger colloidal particles inside.
Step 6: Conclude that dialysis is an effective method for purifying colloidal solutions by removing unwanted small particles.
