Ammonium magnesium phosphate hexa-hydrate usually looses its water of crystallization in a gradual manner. At the temperature above 100 degree Celsius the compound would have lost all its water of crystallization.

Answer:

T = 100 C (212 F)

Explanation:

'Water of hydration' is the terminology used to refer to the water molecules present in the crystals of a given substance that can be removed by heating the substance without altering its composition.

MgNH4PO4.6H2O is essentially magnesium ammonium phosphate which has  6 molecules of water of hydration. These can be removed stepwise by gradually increasing the temperature. At a final temperature of 100 C or 212 F the compound will lose all water of hydration.
