The correct Answer is:
To solve the question, we need to analyze both statements carefully. ### Step-by-Step Solution: 1. **Understanding Statement 1**: - **Assertion**: "Dispersed phase particles of colloidal solution cannot pass through ultra-filter paper." - **Analysis**: Colloidal particles typically have sizes ranging from 1 nanometer (nm) to 1000 nm. Ultra-filter paper has a pore size of approximately 10 nm. Since colloidal particles can range up to 1000 nm, they cannot pass through ultra-filter paper. Therefore, this statement is **true**. 2. **Understanding Statement 2**: - **Reason**: "The size of colloidal particles is larger than the size of true solution particles." - **Analysis**: True solutions consist of particles that are generally less than 1 nm in size. Given that colloidal particles are larger (ranging from 1 nm to 1000 nm), this statement is also **true**. 3. **Conclusion**: - Both statements are true, but the assertion (Statement 1) is not supported by the reason (Statement 2) because the assertion is actually true. Therefore, the correct answer is that Statement 1 is true, and Statement 2 is true, but Statement 1 does not explain Statement 2. ### Final Answer: - **Statement 1 is true, Statement 2 is true, but Statement 1 does not explain Statement 2.**
