The methods of analysis is necessary to be very reproducible; consequently the analysis protocol will be the same in all laboratories. Weighting before the elimination of water or other volatile compounds is an important source of errors. Weighting at constant weight is a general rule in analytical chemistry.

What is the effect of incomplete drying on melting point determination?
The melting point will be lowered and broadened. Incomplete drying of a sample may result in the presence of impurities. When impurities remain present in a sample, the melting point is both lowered and broadened. For example, if the normal mp of a substance is 104C - 106C, an improperly dried substance may contain impurities thus lowering and broadening the melting point range to something like 85C - 97C. (Note: these numbers are just arbitrarily chosen for the purpose of the example).
Is rock salt a drying agent?

What is safe reliable method of drying the crystals?

Formula for calculating drying rate?
Drying rate is not constant throughout the drying process. Drying rate generally decreases with the decrease of free moisture content. ( water in food is present in different forms; bound and unbound.Its easy to remove unbound moisture. In a drying curve, there's a constant rate drying period and a falling rate drying period. Depending on the equilibrium moisture content, critical moisture content and the final moisture content there are different formulas for calculating drying rates.
What is the purpose of drying a sample in analytical chemistry?
The purpose of drying is to lower the moisture content in order to guarantee conditions favourable for storage or for further processing or handling of the product.The purpose of extraction and drying is to obtain samples that are free of hydrocarbons, water and soluble salts that are suitable for further analysis.

WHAT OR DEFINE constant weight?
The term “constant weight” , used in relation to the process of drying or the process of ignition, means that the two consecutive weighing do not differ by more than 0.5 mg, the second weighing being made after an additional period of drying or ignition under the specified conditons appropriate to the nature and quantity of the residue (1 hour is usally suitable
