Given below are two statements, one is labelled as Assertion (A) and the other as Reason (R).
Assertion (A): A solution of table salt in a glass of water is homogeneous.
Reason (R): A solution having different composition throughout is homogeneous.
Select the correct answer from the code given below:
- A(A) is false but (R) is true
- B(A) is true but (R) is false
- CBoth (A) and (R) are true but (R) is not the correct explanation of (A)
- DBoth (A) and (R) are true and (R) is the correct explanation of (A)
Show answer and explanation
Correct answer: (b) (A) is true but (R) is false
Explanation
A homogeneous solution has the same composition and properties throughout, like salt in water.
Table salt fully dissolves in water, giving a true, uniform mixture, so Assertion (A) is true.
Reason (R) wrongly says differing composition is homogeneous; that defines a heterogeneous mixture, so R is false.
