Question

Given below are two statements, one is labelled as Assertion (A) and the other is labelled as Reason (R): Assertion (A): A solution of table salt in a glass of water is homogeneous.
Reason (R): A solution having same composition throughout is heterogeneous. In the light of the above statements, choose the most appropriate answer from the options given below:

• A. Both A and R are correct and R is the correct explanation of A
• B. Both A and R are correct but R is NOT the correct explanation of A
• C. A is correct but R is not correct
• D. A is not correct but R is correct

Hint:

Homogeneous = Uniform composition; Heterogeneous = Non-uniform composition.

Answer 1

The Correct Option is C

Step 1: Concept
Understand the definitions of homogeneous and heterogeneous mixtures.
Step 2: Analysis of Assertion
A salt solution is a true solution where the solute particles are uniformly distributed. Therefore, it is homogeneous. Assertion (A) is correct.
Step 3: Analysis of Reason
By definition, a mixture that has a uniform composition throughout is called homogeneous, whereas one with non-uniform composition is heterogeneous. Thus, Reason (R) is incorrect.
Step 4: Conclusion
Since A is true and R is false, option (C) is the right choice.
Final Answer:(C)
