calculated value for the number of hydrating water molecules would increase above its true level, because the total weight loss would be greater than expected.following are the signs
) loss of water of hydration usually occurs at a considerably lower temperature than decomposition of the salt
 dehydration often results in a change of appearance of the sample
the weight of the sample decreases to a constant stable value
 the calculated number of molecules of water lost should take an integer value
