Question

What is the best method for removing water from a hydrated compound?

Answer 1

Answer:

• Heating to remove water of crystallization
• Passing through a drying agent (deliquescent or hygroscopic substances)

Explanation:

If solid/crystals, compound can be dried by applying heat to remove the water of crystallization.

Drying agents are also utile in removing moisture from compounds in a dessicator. Substances which absorb water from air can be used as drying agents for gases. For instance, $CaCl_{2}$, CaO or silica gel is suitable for drying gases, depending on reactivity of the substance.

Answer 2

Answer:

Heating is the best method

Explanation:

When a mass of crystals containing Water of crystallization is heated sufiiciently to a high temperature, water vapor may be driven off the crystals by the action of heat alone.
