Answer
A is true but R is false.
Explanation — Iron (III) chloride is highly deliquescent that means it is a substance, that absorbs moisture from the air and dissolves, becoming a liquid. So it is kept dry in a moisture proof container with the help of fused calcium chloride (drying agent). Hence given assertion (A) is true.
Reason (R) is false because iron (III) chloride being deliquescent, dissolves in water to form liquid solution whereas hygroscopic substances absorb moisture from the air, but do not dissolve in it.
