Other common desiccants include activated charcoal, calcium sulfate ( Drierite ), calcium chloride, and molecular sieves ( typically, zeolites ).
2.
The gas then exits, first passing a drying agent ( here CaSO 4, the common desiccant " Drierite " ).
3.
Modern'open system'photosynthesis systems remove the and water vapour by passage over soda lime and Drierite, then add at a controlled rate to give a stable concentration.
4.
I don't know a measure of its absolute strength, but in my experience it's harder to dry copper sulfate than it is to dry other inorganic solid desiccant ( molecular sieves, silica, or indicator-doped drierite ).
