    Mar 21, 2016 3. Magnesium sulfate (n=7, e=2.8 mg/L) is a slightly acidic drying agent. It works well in solvents like diethyl ether, but not as well for ethyl acetate. It is a fast drying agent, in part because it comes as a fine powder with a large surface area. 4. Sodium sulfate (n=10, e=25 mg/L) has a very high capacity and is mainly used for very wet

    Magnesium sulphate is a salt with exactly the same number of magnesium cations (with double charge: Mg++) and sulphate anions (also with double charge, SO 4 =) so that the formula is MgSO4. Calcium chloride is made of calcium ions (with 2 charges, Ca++) and chloride ions (with 1 charge only, Cl—). You need 2 chloride anions to balance each
