CHANDRAKANTH · Accepted Answer

## CORE INFORMATION
✓ **Answer**: [B]
## CONCEPT FRAMEWORK
	**Primary Concept**: Separation of Colloids
	**Related Topics**: Colloidal Solutions, Purification Techniques
	**Prerequisites**: Basic understanding of colloids and separation methods.
## SOLUTION PATHWAY
**Given Information**:
	*  The question is asking about a specific separation technique.
	*  We are separating colloids from molecular sized particles.
**Method & Steps**:
	1.	Identify the process associated with separating colloids from smaller particles.
		Reasoning: The question requires recall of a specific term.
		Formula/Rule: None.
	2.	Recall that dialysis is the process of separating colloids from molecular sized particles using a semi-permeable membrane.
		Working: Dialysis uses a membrane to selectively filter based on size.
		Key Point: Dialysis specifically aims to remove smaller particles from a colloidal system.
	3.	Select the correct option
		Result: The correct answer is Dialysis.
		Verification: The definition of dialysis matches the question description.
 ## OPTION ANALYSIS
[A] :x: Photolysis is the decomposition of a substance by light.
[B] ✓: Dialysis is the separation of colloidal particles from molecular dimensions using a semi-permeable membrane.
[C] :x: Pyrolysis is the decomposition of a substance by heat.
[D] :x: Peptization is the process of converting a precipitate into a colloidal sol.
 ## LEARNING AIDS
	**Common Mistakes**:
		1.[Confusing terms]: [Pay attention to the specific definitions of each separation technique.]
		2.[Guessing]: [Review the different methods of separation.]
	**Quick Tips**:
		1.[Memory aid]: Remember 'dialysis' is about 'separating' using a membrane, similar to kidney function.
		2.[Context]: 'Colloids' and 'separation' should immediately direct you to possible methods like dialysis.
