Assertion (A): A solution is a heterogeneous mixture of two or more substances with variable composition.
Reason (R): The component of a solution that dissolves is called as solute, while the other component in which the solute dissolves is called a solvent.
- Both A and R are true and R is the correct explanation of A.
- Both A and R are true but R is not the correct explanation of A.
- A is true but R is false.
- A is false but R is true.
Answer
A is false but R is true.
Explanation — A solution is a homogeneous mixture, i.e., its composition is uniform throughout. It is not a heterogeneous mixture. So, Assertion (A) is false.
In a solution, the substance which dissolves is called the solute, and the substance in which it dissolves is called the solvent. So, Reason (R) is true.
Therefore, Assertion (A) is false but Reason (R) is true.
