the temperature at which the residu

the temperature at which the residue is dried has an important bearing on results. because weight losses due to volatilization of organic matter, mechanically occluded water, water of crystalli-zation, and gases from heat-induced chemical decomposition, as well as weight gains due to oxidation, depend on temperature and time of heating. Minimize opening desiccator because moist air enters. Some samples may be stronger desiccator than those used in the desiccator and may take on water.
