Answer
A is true but R is false.
Explanation — Sodium chloride and potassium chloride can be distinguished using flame text. Sodium salt produces golden yellow flame and potassium salt produces lilac flame. Hence, the assertion (A) is true.
Sodium salt produces golden yellow flame rather than red flame and potassium salt produces lilac flame. Hence, the reason (R) is false.
