what is azeotropic drying

At the time of harvesting the moisture content in grains and seeds varies from 15-35%. Besides, grains have a tendency to absorb moisture from the atmosphere. If the moisture content is high, seeds are prone to be infested with pests and this in turn will decrease their quality. Hence moisture con..

Azeotropic Mixtures - In case of solutions showing positive deviation from Raoult's law, at one of the intermediate compositions, the total vapor pressure is the highest and the boiling point is the lowest. Similarly in case of solutions showing negative deviations from Raoult's law, at o..

Drying Agents - Substances that are capable of taking away moisture from a gas are called drying agents. As all deliquescent and hygroscopic substances have affinity for water, they can be used as drying agents. However, usually anhydrous calcium chloride, quick lime a..

We know that there is water vapour in air. In other words, air contains moisture and so it is wet. This quality of wetness is referred to as humidity. For our physical comfort, humidity should not be too high or too low. Usually when the atmospheric temperature is high, more evaporation of water ta..

These are substances that are capable of taking away the moisture from a substance. Since all deliquescent and hydroscopic substances have affinity for water, they can act as drying agents. Usually anhydrous calcium chloride, quick lime and concentrated sulphuric acid are used as dr..

When the crystals are unstable, they are gently pressed between the folds of filter papers, and are finally placed in a vacuum desiccator to obtain dry crystals. If the substance is stable and has a high melting point, the crystals are pressed between the fold of the filter paper and are..

Quicklime. (CaO). Quicklime being basic in nature does not react with basic ammonia gas. But absorbs moisture (CaO + H 2 O g Ca(OH) ..

It is the compact form of the Leclanche cell. Anode - Cylindrical Zn container. Cathode - Central Graphite rod. The space in between is filled with NH 4 Cl and ZnCl 2 . The graphite rod is surrounded by MnO 2 and carb..
