Aoa/Hi.
Is calcium chloride used as a drying agent to dry ammonia(gas)? Why? ..and why isn't water used?

This is regarding a mistake i did in paper 4.
there was a diagram for exorthermic reaction, and we had to complete it by writing the products and enthalpy change.
instead of writing the real products i wrote only PRODUCTS. Because i was confused!
Will that score any mark?? or do we have to write the specific products to gain the mark?

Aoa/Hi.

how can you use water for drying ? CaCl2 absorbs water from ammonia n it is highly used for drying of amines ammonia alcohols ketones etc
