Question

which group 2 salts are used as drying agents and why??​

Answer 1

Answer:

2. Calcium sulfate (n=0.5) is a neutral and good drying agent. However, it does not have a high capacity, which makes it useless for very wet solutions. ... Potassium hydroxide (KOH, n~1) and potassium carbonate (K2CO3) are both of basic nature and often used to dry basic solutions containing amines.
